I've just updated to Xcode 9 and am getting App installation failed Could not write to the device error popup every other time. I see there are older questions on the subject, but this one is particular to iOS 11 and Xcode 9. I've never had the issue before.
How do I make sure Xcode 9 can install app to device every time?
In my case this issue was caused by using App Store distribution certificate while iPad was connected wirelessly.
Switching to development certificate fixed the issue.
Xcode 9 seems to have many different manifestations of this problem. Some of the other answers address specific problems, but this definitely occurs when there is nothing wrong with your project. These steps always resolve for me (in order from least painful to most painful):
Try running it again. Sometimes it works on the 3rd or 4th time.
Unplug the device and plug it in again.
Restart Xcode.
Clean build folder (not a regular clean - this is cmd+option+shift+K or hold option in the product menu) and then rebuild.
If all else fails, once a full restart fixed it for me. But probable something else was the root cause.
Hopefully Xcode fixes these problems soon...but I'm not hopeful.
In my case, I want to testing watchOS app and I set the debug provisioning profile to release one. I set to automatic and the issue is gone.
The solution that works for Could not write to the device is clicking the run button again after dismissing this error message.
In some cases I get the error App installation failed: unknown error. In this case I need to do a clean before building.
Deleting the app from device also helps.
I had similar issue and got is solved using below steps :
Delete app from device
Disconnect device from system
Restart iPhone device and Xcode
Delete derived data content
Clean your project (Shortcut key : cmd + shift + k)
Rebuild your project
I am facing same issues on my iPad. It was working fine before. But after some time my development version stop working on iPad. I have tried and search on internet but not able to find solutions. I have tried all above cases but no Luck.
At last, I have found solutions. Some developer has changed DATE/TIME settings for my Ipad. Please check date/time because my Provisional profile for apps has expired for the manual date set on iPad.
Hope the following steps will be useful for others,
Check your provisioning profile is valid.
choose the debug profile for signing in target.
Open you scheme under product in menu toolbar or using Cmd + < shortcut.
Choose debug mode for Run in your product scheme.
Tadaa! now you can run the app in your device flawlessly.
Happy coding! :)
I tried all the method , they didn`t work for me .
And I fixed the problem by removing the soft link file made by ln -s
In my case, this issue appears when I added a folder as reference in the project which contains a symlink. Removing the symlink fixed the issue.
Mine occurred when I had not signed in using my itunes developer portal credentials to sign into XCode. When I did it and cleared all derived data, it worked out.
Everyone is solving this problem in a different way. Mine was changing executable name, building the app (throwing the "You don't have permission etc." problem) and changing the executable name back to the original value.
I don't know why but it worked.
I actually had to reboot the system on the Mac, this gets me rid of the problem for a good while, but it eventually comes back. None of the other solutions mentioned here worked for me.
In my case the problem appears while I use manual signing and try to debug the app in Release mode. Although the fastlane builds and uploads fine in this mode fine, direct XCode debugging fails with the error "Could not write to the device". Temp switching to automatic signing mode fixed this issue.
What worked for me:
delete the app from iPhone
clean the code in Xcode
quit Xcode
re-open Xcode, connect my iPhone, and run it again
I got this issue App installation failed - Could not write to the device and I solved it by doing the below steps
Uninstall the app from device.
Clean the project.
Run the project.
It worked for me.
Xcode 9. iOS 11 SDK. Watch SDK 4.x.x - OPEN THE WATCH APP on the iPhone after failed. My Watch tab->(scroll down to the bottom)-> Install your app. Hope this helps. Just need permissions from the "Watch" app.
I had the same question that could be solved by deleting other debug App from my iPhone, then it worked.
When I choose the Automatically manage signing, my problem fixed.Hope my answer can help you.
Sometimes the problem arises when you removing some pod file reference. The only way to solve this in also your pod-file
eg:
use_frameworks!
pod 'KYDrawerController'
pod 'GoogleMaps'
pod 'GooglePlaces'
pod 'Alamofire'
pod 'Firebase'
pod 'Firebase/Messaging'
remove the unwanted file in this place. And also reinstall the pod-file again and open your project it surely works for you.
This question already has answers here:
Unable to run app in Simulator : An error was encountered while running (Domain = LaunchServicesError, Code = 0)
(19 answers)
Closed 5 years ago.
I received an error (Domain = LaunchServicesError, Code = 0) when trying to launch my app in the iOS Simulator with Xcode 6. I looked for solution in google, but I didn't find anything practical.
What does this error mean?
This error indicates that there was a problem with installation. Unfortunately, Xcode does not actually print the contents of the error message that would give you more insight, but you can look at ~/Library/Logs/CoreSimulator/CoreSimulator.log to see the rest of the error details. There will also be more information about the problem in the simulated device's system log (~/Library/Logs/CoreSimulator/[Device UDID]/system.log); look for messages from installd around the time of the error).
Common causes for this include bundles missing an Info.plist, missing keys within your bundle's Info.plist, or values for some keys in the Info.plist not being allowed.
If your app's Info.plist does not contain a valid CFBundleVersion key/value pair, it is possible that your app may install correctly the first time but fail to update. Many users seem to work around this by doing a "Reset Contents & Settings" after each install, but it would be better to fix the root cause by setting an appropriate CFBundleVersion in the Info.plist. I believe iOS 8.2 now correctly returns an error on the first install in this case rather than just on updates, so hopefully this problem will be more obvious now.
Users with home directories on file systems that do not support hard links (eg: network home directories via AFP, SMB, or some NFS servers) may also run into problems related to hard linking. If this is the case, I suggest you create a path on your local HFS+ filesystem for simulator development (eg: /var/simulator/[user]) and create a symlink to that path from ~/Library/Developer/CoreSimulator. This particular issue was fixed in one of the iOS 8.2 betas.
In another case, the Build&Run would always succeed on the first try, but subsequent attempts would sometimes fail due to a changed Info.plist (eg: because someone's build system settings result in CFBundleVersion being different on each iteration). You can usually recover by either deleting the installed app (using a long-press from the home screen or xcrun simctl uninstall [Device UDID] [app identifier]) or erasing the device back to a default state. To erase the device, execute xcrun simctl erase [Device UDID] from terminal or choose Erase Contents & Settings from the iOS Simulator menu. This particular issue was fixed in one of the iOS 8.2 betas.
A newer instance of this issue is occurring for Xcode 6.2 users. If you have a WatchKit App Extension bundled in your app, it will fail to install to versions of the iOS Simulator runtime older than iOS 8.2. As a workaround, you will need to manually disable the app extension from installing when you want to test with iOS 8.1 and earlier runtimes.
If you need more specific help, please provide the entirety of the error message from CoreSimulator.log and any messages from installd and CoreSimulatorBridge that appear around the same time in ~/Library/Logs/CoreSimulator/[Device UDID]/system.log as that will reveal the underlying problem.
Does your project include a widget or extension? If so, the problem could be the bundle identifier of your widget/extension. It should be the same as the main target, appended with a period and an extra string. So for example:
Main target: com.mycompany.myapp
Widget should be: com.mycompany.myapp.widget
I fixed it by resetting the simulator:
iOS Simulator > Reset Contents and Settings...
Since everyone writes what they went through and how they fixed their exact problem, that might be unhelpful.
The problem is that there are different causes for the same error message and the right way of solving it is to open up ~/Library/Logs/CoreSimulator/CoreSimulator.log and look in there for the last message. This message gives you a good clue and sets you on the right path of solving your problem (sometimes it's bundle IDs, sometimes it's a missing or an extra attribute in the Info.plist, but you always get a good, descriptive clue).
This is how you narrow down the problem and eventually get to fix it.
Good luck and tough nerves with Xcode .)
Z.
For me I just cleaned the project and it worked -> Product -> Clean
TLDR: Clear your Project Build Folder - and you will be free of this pain.
( plus I logged this as a bug with Apple as they need to find a way to fix this in Xcode )
None of these solutions worked for me - I banged my head against several walls.
I looked at the CoreSimulator log and I realised that it was trying to build a library that I had deleted.
I couldn't find references to it anywhere.
Then I saw via another SO Question which unfortunately I can't find to reference, if you:
Hold down your option key then Product-> Clean option becomes Clean
Build Folder
Press that and enjoy having your error vanish
"Reset Content and Settings" from iOS Simutalor menu options and launching simulator after Quitting solved my issue.
In XCode 6
An error was encountered while running (Domain = LaunchServicesError,
Code = 0)
I had this error after making some major code changes to accommodate the iPhone 6 Screens. in Xcode 6 (iOS8)
I followed the options above and found that the only way to really get this fixed was by doing the following:
Deleted the derived data [go to Window >> Organizer >> (Find your App) Click on Delete next to the Derived Data]
Product >> Clean
Reset Contents and Settings in Simulator
Changed the Bundle Version to 1.4.1 from 1.4 in pList
Thank you for all the previous answers that got me to this stage. It worked a charm!
In my case, the error was caused because i didn't set the build id.
Setting this, launches the emulator without problem.
One other thing to try, that worked for me, after resetting the simulator and doing a clean build did not help, is clearing out the derived data. To do this: go to Organizer click on project click on delete derived data button. I had this happen after working on an extension for a while and went back to the regular branch. Hope this helps.
This is what caused the problem for me: the build number for the main app and the extension were different (I had incremented the main app build number to 1.0.1.03, but left the extension at 1.0.1.02).
Making them match fixed the problem for me.
Open the Console app and look there. In my case it told me exactly what to do. I saw:
ErrorDescription=WatchKit 2 app extension's NSExtension.NSExtensionAttributes.WKAppBundleIdentifier value does not match WatchKit app's bundle ID (found "com.myCompany.MyApp.MyApp.watchkitapp"; expected "com.myCompany.MyApp.watchkitapp").
So, I went to each plist and checked any items that related to a BundleID. Then Clean, relaunch, etc.
My case was about framework compilation. I have enabled the 'copy only when installing' option from Target- Build Phases- Embedded Frameworks-
I have an app that is set up to use different bundle IDs based on the build configuration. When creating my Apple Watch extension, Xcode generated everything using my Release ID, so I had to go through and change it all manually for debugging. Here's all the places I had to change it:
WatchKit Extension's Build Settings -> Packaging -> Product Bundle Identifier
WatchKit Extension's Info.plist -> NSExtension -> NSExtensionAttributes -> WKAppBundleIdentifier (this needs to use the same prefix as your companion app)
WatchKit App's Info.plist -> WKCompanionAppBundleIdentifier
The last one took me a while since the WatchKit App's Info doesn't show up as a tab when viewing the target settings, I had to go direct to the Info.plist file itself.
Try putting some number into [TARGETS]-[General]-[Identity]-[Version(or Build)], if they are empty.
It worked for me.
I hope it will help you.
I also have this error. In my case the log ~/Library/Logs/CoreSimulator/CoreSimulator.log was something like that :
Could not hardlink copy /Users/myUser/Library/Developer/CoreSimulator/Devices/60E569E7-6750-428A-A401-841BB081xxxx/data/Containers/Bundle/Application/70F24DDC-7954-46BF-B799-F807FD98yyyy/myApp.app to /Users/myUser/Library/Developer/CoreSimulator/Devices/60E569E7-6750-428A-A401-841BB081xxxx/data/Library/Caches/com.apple.mobile.installd.staging/temp.kOrJ9G/extracted/Payload/myApp.app with manifest /Users/myUser/Library/Developer/CoreSimulator/Devices/60E569E7-6750-428A-A401-841BB081xxxx/data/Library/Caches/com.apple.mobile.installd.staging/temp.kOrJ9G/extracted/com.apple.deltainstallcommands.com.mycompagny.myapp
thanks to this answer In look at my app info.plist. the key CFBundleVersion was missing so I add it and now everything is working !
None of the above worked for me, but this did:
I simply deleted IceCream.xcworkspace/xcuserdata/xcuserdatad and then reset the simulator and ran the app again. (Reseting the simulator alone, did not work for me.)
"Reset Content and Settings" from iOS Simutalor menu options and launching simulator after Quitting solved my issue.
The great explanation by Jeremy at least set me in the right direction, but despite having all the bundle identifiers and versions set correctly, the error still persisted. I then checked the Apple documentation which shows that the WatchKit extension (in its Copy Bundle Resources phase) copies the WatchKit app. This WatchKit app was named exactly the same as my iOS app, causing Xcode to confuse the two and read out the wrong plist, thinking the bundle identifier was incorrect. Renaming the Product of the WatchKit app to something distinct finally solved it for me.
If you've changed your bundle ID, make sure you do a clean build before trying to build it again! See how here: How to Empty Caches and Clean All Targets Xcode 4
So it's definitelly .plist problem. In my case it was empty NSExtensionMainStoryboard, removing this property fixed the problem
I had this error whilst trying to build Apple's Lister Xcode Project and run it on the simulator.
The essentials which fixed it for me were:
1) BundleID for the iOS App and the iOS Extension had to be different
2) I provide iCloud and App Groups for both targets
3) I used Xcode's "Fix Issue" to fix the issues
After that I could build and run the app without warnings or errors.
The clue from the log file was "... LegacyErrorString=DuplicateIdentifier, FunctionName=-[MIInstallableBundle performPreflightWithError:], SourceFileLine=450, NSLocalizedDescription=The parent bundle has the same identifier (com.ACMECompany.Lister) as sub-bundle at /Users/stephen/Library/Developer/CoreSimulator/Devices/5329928B-946B-40A4-B666-EFD11B96D11F/data/Library/Caches/com.apple.mobile.installd.staging/temp.HQ5d9X/extracted/Lister.app/PlugIns/Lister.appex"
Had a wrong app version set in InfoPlist.strings localization file. Urgh!
An hour gone!
Delete your simulator and regenerate one.
It works for me.
I removed the key in watch app's .plist file that shouldn't have been there. And the problem disappeared.
This worked for me:
In project settings -> General tab -> Identity section I changed the Version number from something like 2.0.2 (three digits) to 2.0 (two digits) then I deleted the app in the simulator and run the project again. No more error after that.
One other possible solution to add to all of the others that will no doubt stay above mine ;)
I deleted & later reinstated a Today Extension target retaining the source files, but after trying every solution under the sun, I realised it didn't have any sources or resources in its target! You might encounter this as well if your detailed launch services error can't find your compiled app extension file.
So, long story short, make sure your target has something included to compile or bundle in there. You can check your target memberships by selecting the relevant file(s) on your project navigator (on the left) and setting your checkmark(s) as appropriate in the file inspector (that's the first tab on the right).
I had the following in my log...
<Error>: Error Domain=LaunchServicesError Code=0 "(null)" UserInfo={Error=ExecutableTwiddleFailed...
This was due to there being no source files added in the extension project.
This error was showing up on my system when there was no hard disk space available. I freed up some space on my system for it to work.
My Problem was that the wrapper extension for the target project was unset.
To fix I had to go to target project -> build settings -> Packaging -> Wrapper Extension.
Set this to "app" (No quotes)
This fixed the problem for me
In Xcode 6.3, I got this error when trying to run an iOS project written in Swift on a real device.
App installation failed
could not write to the device.
I tried to clean the project and run again, but the same error occurs.
How can I fix this error?
Deleting the app on the device and running the project again works for me.
I did a Clean and installed my app successfully.
Product->Clean(Shift-Cmd-K)
I turned off the device and turned it on again after which I did not get such error.
OK, few things you should consider that could guide us to the problem, please check and post the answers:
is your project using capabilities? are they set correctly (should be all green)
did you try with a different project (something really simple)?
are you able to install apps from the App Store?
did you check the amount of free space left in the device?
if not, another suggestion will be using exception breakpoint, there is someone that posted an explanation how to setup it, do it and post the logs
App installation failed
I hope it helps you
Got this problem twice in one week on complete different devices.
One device had no more storage left, after deleting some apps the project installed perfectly.
The other device was fixed after rebooting the device
If you are using a free developer account you may need to uninstall some other apps you have signed.
For me it was the provisioning profile - I used distribution instead of development
My issue was an embedded framework.
Go to "Build Phases" -> "Embed Frameworks" -> Check "Copy only when installing", and it got rid of the issue for me.
For me the following did not work on iOS 11 beta 10, XCode 9 beta 6:
Restart the device
Deleting the app from the device
No symlinks were in the project
There was plenty of storage available
Deleted Derived Data and voilá, it worked again
in my project this problem happened because there was a folder with symbolic link. I removed that folder and it worked properly.
This error has many potential root causes, as can be seen by the large variety of suggested answers. The best approach to troubleshooting app installation issues like this one is usually to inspect the console of the iOS device itself, as that'll often provide much more specific error messages. In Xcode open the 'Devices and Simulators' window and take a peek at the logs of the device where your app is being installed.
In my case, the "Could not write to the device" error was being caused by this:
Feb 27 10:54:58 iPhone-7-110 installd(MobileSystemServices)[46] : 0x16f92f000 -[MIBundle _validateWithError:]: 38: Failed to load Info.plist from bundle at path /private/var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.ebmR6U/extracted/SampleApp.app/Frameworks/SomeFramework.framework
Which clearly hints at what's actually going on. I had forgotten to set an Info.plist file for my dynamic framework target (used by the app).
I had a symlink in my project to a file outside of the project. When I deleted this symlink the install worked fine.
I was having the same error, i just deleted the project and fixed!
Go to Window -> Project and right click, and remove from projects!
In the case of your device have an app with the same bundle identifier, Xcode will throw this error.
Try to delete potential app with the same bundle identifier.
Check your provision profile, maybe you are using the app store provision profile like me. I had to change the app store provision profile to development, now it's working.
Tried all of the above answers: Deleting the app, clearing storage space, cleaning the project...
What finally worked was bumping the build number in info.plist (General > Build)
For anyone still facing this Issue:
There are so many reasons and this is one of them as it happened to me.
I've faced the same problem and I was connected wirelessly and If you are trying to install the application in wireless connecting mode (connected through same network), this might probably because of poor internet connection. Check your internet connection and try again, it works fine...
Get rid of embedded libraries, dont' just throw it in there make sure it is embedded indeed.
If you use your iPhone for debug, maybe, because your iPhone's storage space is less than your debug App.
Clean your iPhone --- Real machine
Clean your Mac --- Simulator
This looks like another time waster courtesy of Apple's amazingly high class development team. On iOS11 Xcode9 (pick your beta, any one works) this will happen randomly. Appears to be more frequent if you dare to switch apps while compiling. Just build again and stare at xcode - it'll work the second time without fail in my experience.
Apparently this message can also appear if the system clock of device where the app is being installed is too far away from the current time.
I was doing some tests with date formatters by changing my iPhone's system clock and eventually forgot to reset it to the current time. Afterwards it always displayed the same message ("could not write to the device.") whenever I attempted to run the app. Simply resetting the clock in Settings fixed the issue.
Nothing helped me. I followed the below steps,
Clean derived data folder
Quit Xcode and disconnect device
Restart Macbook
Restart Device
Open Xcode
Clean and run the project
Finally I got it working!!
I am facing same issue then solved out follow this step and now its working.
Deleting the app from the device
Try to install another application
Remove derived data in X-code.
Restart X-Code then clean and build the project then run.
It's still not working then
Remove un-used application
Restart the device and check the Available and capacity in settings
Again app run in device
I hope its worked, enjoy it.
My problem was I had initially installed the app using a different set of developer credentials on the device. Deleting the app from the device fixed it.
Maybe it can be due to the following error App installation failed. No code signature found. In my case after a project clean the description of the error switched to "No code signature found".
In my case I created two frameworks but they had the same bundle identifier.
This caused the installation to fail, so double check the frameworks bundle identifiers and make sure that each of them have a unique bundle identifier.
Environment: Xcode 10
sometime this error occurs due to wrong certificate.Please make sure your certificate.
Also this the error shown if your machine running Xcode is low on space.
Once I had to load an App Container for debugging purposes into an iPad, said operation failed because the container was too big (18 GB) for this device (16 GB minus the OS), so that I desisted the task and completly forgot about it, leaving the failed installation in the device. Later, when trying to install a different application this error appeared, once I got rid of the failed app installation, everything got back to normal.
Basically, your Ipad might be low in storage.
One reason this can happen is if your app bundle contains broken symlinks.
when I run my app on iPad it builds my app and then I got error:
"Could not launch 'AppName', timed out waiting for app to launch".
Though, after this error, app is working perfectly on device. I think that it's caused by some sort of setting "Debug is not allowed" or something like that.
I was having the same problem - Deleting derived data didn't work. In my case I found out that I was building the debug with an Ad Hoc provisioning profile.
Also you might try to Reset Content and Settings within your iOS Simulator or to open the XCode Organzier, navigate to your project and delete all Derived Data. Sometimes these actions help by your given problem.

Xcode has stopped being able to run my app, it started directly after I deleted it from the device and attempted to re-install by rerunning it in Xcode (something I've done hundreds of times before).
It says
"Could not launch XXX.app"
"No such file or directory (/Users/Mylaptop/Library/Developer/Xcode/DerivedData/MyApp-ekxcbebfpzkahtfkujyqkcwprzia/Build/Products/Debug-iphoneos/MyApps.app/MyApp)."
I've rebooted the phone, relaunched Xcode, cleaned everything, rebuilt everything. This error message won't go away.
This is with Xcode 4.5 which I've been using since it became available, if I revert to 4.3.2 then Xcode says "Finished running app" but it doesn't actually do anything - the app is neither installed nor run.
I'm completely stuck - unable to run anything on the device anymore.
Any suggestions?
That is really annoying. This error happens in a number of different situations. Sometimes restarting the Xcode, fixes the problem. If not, follow these steps:
Disconnect your device.
Delete the app from your device.
Quit Xcode (Do not just simply close the window, quit it)
Delete derived data folder (~/Library/Developer/Xcode/DerivedData/-gbrvhlvwmpiobxdujegtghggrffp - or something like that)
Now start Xcode once again, connect device and run the project. It should work fine.
from DhilipSiva blog
Try deleting "Required device capabilities" in the -Info.plist file.
You can't require armv7 on a 3G, and you can't require armv6 on any newer device, so just delete this attribute entirely.
I found the answer. The iOS deployment target's version was not the same as my device's OS version.
First tried some of the above with info.plists and deleting derived data, clean, etc.
My solution: quit XCode, reopen project. Go to derived data in Finder. Deleted data for all projects (was all trashable, but I would try deleting your troubled projectdata first). And then it worked again. Deleting derived data from XCode didn't work.
The following resolved my problem... my app worked for me in debug/release, then I built a few ad-hoc archives and debug/release builds stopped working.
Symptoms:
invalid entitlements errors when launching from Xcode to device (play with entitlements...)
immediate abort with no error (finished running ) when running simulator
could not launch ... directory blabla.../build/product/debug-iphoneos/... not found when launching from Xcode to device.
Eventually after trying to benefit from everyone else's pain I found in Targets [AppName]:
Build Settings
Build Locations
Build Products Path build
should be
Build Products Path build/Products
No idea how this got set incorrectly.
This must be hard-coded somewhere in Xcode/Springboard because 'Products' appears in both Xcode and in the Device console.
This is Xcode 4.5.1.
I solved this problem by
renaming a directory above my XCode project
Changing the name of the project in XCode fixed it for me.
In XCode, under the Project Navigator, click the project name, and it should let you rename it just like a file in Finder. Deleting derived data did not help.
I built my XCode Project with CMake and somehow it (or my stupid self) deleted or emptied the property "Executable file" in the info.plist. I set it back to ${EXECUTABLE_NAME} and it worked again.
Took me really alot of time working through all the suggestions and fixes until I finally found that problem.
Hope this will help some one struggling with the same problem
Edit:
It was in some way CMake messing up my plist file. I created my own Info.plist and used it the following way:
SET_TARGET_PROPERTIES( MyApp PROPERTIES MACOSX_BUNDLE_INFO_PLIST ${CMAKE_CURRENT_LIST_DIR}/MyApp.plist )
Inside my plist I had this entry:
<key>CFBundleExecutable</key> <string>${EXECUTABLE_NAME}</string>
Unfortunately CMake still seems to parse that file and replaced ${EXECUTABLE_NAME} with an empty string since its the CMake variable syntax. My quick work around is the following:
SET( EXECUTABLE_NAME "\${EXECUTABLE_NAME}" )
Now it works like a charm.
I am probably alone with exactly this problem, but who knows.
I had the same problem, but in my case I had a wrong requirement in my info.plist (require gyroscope for an iPhone 3Gs)
I tried to run my project on a different system other than that on which it was developed. I was getting “Could not launch xxx.app: .. No such file..”.
Removed the app from the device and then deleted the derived data from organizer in xcode for the app.
Organizer-->Projects-->Derived DAta-->Delete
My problem was resolved.
You need to set the deployment target LOWER than your device's version
For me, the solution was just to use the correct (non-distribution) provisioning profile.
I was defaulting to always using my ad hoc provisioning profile, but then I changed to using my developer profile (team profile) and that solved things. I went ahead and cleaned out the Derived Data directory to be safe but I don't know for certain if it is required.
XCode used to have a warning that told you to use the correct provisioning profile but that error message seems to have gone away in XCode 4.5.
I've had this problem by a very strange solution.
My problem was slightly different as I have 2 Developer certificates in Keychain. We have two developer accounts (lets say AD and BD).
1) I did change Bundle identifier from com.BD.game to com.AD.game
2) Device on which I had problems was only signed in AD provisioning profiles.
3) I was unable to debug the game on iPad - although the device had valid provisioning profiles, I had valid certificates, I restarted Mac, device, reinstalled Xcode ... nothing helped.
Do what i did today was examining the project.pbxproj file for any strange entries.
What I found was that Xcode was using proper provisioning profile, but signed the ipa/app with wrong certificate.
"CODE_SIGN_IDENTITY[sdk=iphoneos*]" = "iPhone Developer: **BD** (XX******)";
After I manualy corrected the name and id; everything works like charm.
I got the same error. In my case I was set deployment target as 6.1 and trying to run an iOS 5.1 iPad. When I changed my deployment target to 4.3, issue solved.
Still having the problem . Try this
Disconnect your device.
Delete the app from your device.
Quit xcode.
Now start Xcode, connect device and run the project. It should work fine.
For me (using IOS 7 and Xcode 5), the error went away right after I did "Add to Member Center" with my device in the Organizer.
I would like to mention that the easiest way to open the DerivedData folder in Finder is the following:
Open the Organizer.
Click on "Projects".
Select your problematic project.
Next to the path of the DerivedData, click on the little right-arrow button.
Deleting the contents of the DerivedData folder worked for me. Instead of using the "Delete..." button, you should have more success deleting the files manually through Finder.
Go to: your project Target - > Info and from CustoM iOS Target Properties remove the Required Device Capabilities.
In my case that were armv7 and armv7s.
After that the app was built successfully on my iPhone 4.
This is how it looks after i removed both of requirements
For me, I forgot that I had "telephony" in the "Required device capabilities" in the info.plist. Removed that, and it finally worked on my iPad.
For me restarting of Xcode, cleaning DerivedData and restaring device wasn't enough in most cases, until I had figured out that iTunes was also running, and after quitting iTunes everything worked fine!
So my steps now are simple:
1. Quit Xcode.
2. If iTunes is running, quit iTunes.
3. Reopen project.
No need to remove app from the device, clean project or restart/disconnect device.
I think that's because Xcode and iTunes use some common libraries (as you know, Xcode Installer always asks to quit iTunes on installing iOS SDK).
I had this problem and tried a number of the suggestions which didn't work for me - then I found the one about removing the "Required device capabilities" in the -Info.plist file (which for me included location-services & gps)
That worked!
I then re-added them and it still worked.. go figure.
This was xCode 4.6.1 & my app is developer with Phonegap/Cordova
I tried all the above and yet it still wouldn't run. I fixed the problem by changing the derived build location. File>Project settings>"derived data location" change to project-relative. Or you could just make sure the default path has permission to read/write.
My issue seemed to be picking picking Portrait (top home button) as Item 0 in Supported Interface orientations in my plist. Removing that or moving it down seemed to fix my problem. Go figure.
I had this problem too for a Universal app with Xcode 4.5 on my iPhone ONLY, where I had two debug devices:
iPhone 4 iOS 5.1.1
iPad 1 iOS 5.1.1
The Info.plist had an empty entry under "Required device capabilities"
I know that I did not enter this empty 'Item 0'. The app loads on the iPhone
since I removed the empty item. I did not encounter
this problem on any of several earlier versions of Xcode,
This means that Xcode 4.5 handles this 'inserted' item differently
for the two devices I use. I have been wrong before, but this does seem
like a bug in Xcode 4.5.
This may seem obvious but you must also set your deployment target to the operating system that your device is running.
So if you upgrade to iOS 6, it will set your deployment target to iOS 6. You'll need to deploy to 5.1 if the device you are testing on still runs 5.1.
My issue finally got resolved by checking to make sure that the productName attribute in the /* Begin PBXNativeTarget section */ section of my project.pbxproj file matched the name attribute.
Once editing it so that they were the same, Xcode finally runs the app on my device correctly!
Thanks to Max Weisel for helping me! :D
Deleting the derived data folder did not help for me.
Using Xcode 4.4.2 the only solution was to open Organizer and delete old expired and extraneous provisioning profiles on the iDevice. Then everything worked perfectly again.
This may be a red herring, but I experienced these problems when I added custom launch images before deleting the default ones. Deleting the default launch and custom images and then adding back in the custom ones fixed it for me. I'm working with iOS 6 and Xcode 4.5.2
There seems to be a few different things that can cause this very helpful error message.
For me, it was down to an incorrect "Required device capabilities" in the Info.plist. I had added a blank array item by mistake (on top of the the architecture, armv7).
Deleted the blank array item and now everything is fine!
I had this problem and nothing really helped except:
My problem started after changing the contents of my info.plist and no reverting had helped.
What solved it for me was:
Create a vanilla info.plist in a brand new project
replace the old info.plist with the new
renaming it (like app_info.plist)
Set Build Settings/Packaging/INFOPLIST_FILE to be the new one.
Make all the changes you need for your project
Hope that helps. I tried everything else suggested here and this was the only solution for me.
Facing same problem but now problem is solved, i deleted Executable file info.plist. I set it back to ${EXECUTABLE_NAME} and it worked again.. :)
In my case i just set 777 permission directly to xxx.app folder to all files and work!
