I'm using the release version of xCode 8 and am trying to run my app on the simulators. They are all the iOS 10 simulators.
No matter which simulator I use, when I run the app the app icon shows up in the simulator but then that's it. The app never displays in the simulator. I only see the app icons of the iOS home screen.
I put some break points in my initial view controller at the viewDidLoad, viewWillAppear, and viewDidAppear methods. All of them triggered. So as far as my app is concerned, it is displaying on the device. I also get all the normal log output and networking calls happening just fine. It even shows the popups for permission to access the calendar and notifications. But my app is not brought to the foreground.
If I then click on the app icon in the simulator, my app runs normally. But it should be automatic when I hit run from xCode.
When I run my app on an iOS 10 device I get the same behaviour as all three of those view methods are called. However I don't get any of my normal log output. In fact I don't get any log output. However the app was already installed from when the device was on iOS 9.x. Not sure if that is a factor. But aside from the simulator issues, this is the bigger issue.
I've tried cleaning the build, deleting the app, I even tracked down the derived data folder and deleted that from the simulator. None worked. I also updated all my cocoa pods I have installed too.
Any one else experienced this?
That sounds weird but I read a lot of threads on the Apple Developer Forums on the same problem during the different Xcode 8 beta version, try these steps:
reset the simulator using the menu "iOS Simulator" -> "Reset Content and Settings..."
remove your 'xcuserdata' directory inside your .xcodeproj directory
do a clean build folder (hold down option key when selecting clean)
reboot your Mac
If these steps don't solve anything you can try this solution:
Copy-paste Xcode-beta.app from Applications folder to somewhere else, e.g. - Documents folder.
Delete Xcode-beta.app from Applications folder.
Move Xcode-beta.app from Documents to Applications folder again.
originally posted here, obviously using your Xcode.app instead of Xcode-beta.app.
I am using xcode 7.1 and trying to upload my app to the app store directly through xcode. While uploading I am getting a weird error:-
cannot verify client 3000
Note:- I recently made changes in the accounts (xcode preference section). Is this related to my error?
I also restart the xcode but issue still there?
I already checked this question on SO, but they say restart your xcode. But this does not solve my problem.
For my case,I got this error after selecting "Generic iOS Device" when archiving, however i plugged in my iPhone and selected it, then archived, I got no errors this time.(I also cleaned both Shift+cmd+k and Shift+alt+cmd+k before archiving)
I encountered the same issue the first time I tried to submit to app store with the target on my device.
What worked for me:
I retried a couple of minutes later without changing a thing and everything went smooth.
This is temporary apple server bug. Try it again OR Retry after some time it will fix the problem.
Thanks
There is no need to reinstall Xcode. Just wait a few minutes and try again and it will work.
I tried :
waiting days,
restarting,
deleting the developer account in
preferences,
submitting archives from a connected device,
submitting
archives from a iOS generic device.
Nothing worked.
I needed to:
create an archive (it was from a connected device),
in the organiser window select the export button (on the right hand side underneath the "Upload to App Store" button.
Select that the export is for app store distribution.
Wait.
Take a note of the location the .ipa file is saved to.
Go back to Xcode, then select the menu item Xcode > Open Developer Tool > Application Loader.
Select Deliver Your App, and select choose.
Navigate to your .ipa file noted above.
Select next, wait, next, check for any error message, send.
Hope this helps someone.
I got this error while uploading my distribution archive to App Store with selecting Distribution provisioning profile scheme -> Product -> Archive -> Upload to App Store. The error is based on I chose my real iphone device in Xcode by mistake. You need to choose "Generic iOS Device" and repeat same steps as I mentioned before.
You have to plug in your iPhone to your Mac and try to upload to AppStore again.
For some reason, validating the archive before uploading fixed the issue for me.
With Xcode 7.1, I could only make a successful build without bitcode. Try it out if everything else fails.
I resolved this by exporting ("export" in xcode archive organizer -> "to iOS App Store") and using the Application Loader instead of xcode to submit.
It is recurring. Seems to me like an internal error with apples identification service or so.
My definite solution:
Get yourself a cup of tea and try it again.
You can, of course, do some voodoo or change the target device or something, but re-trying after a while will do.
I have the same issue.
I did the below steps:
Step 1: Select Code Signing Identity for "Release"
Step 2 : Select Distribution profile
I tried to use Application Loader instead and it worked well. Maybe that helps
I've been having this problem since Xcode 7.1 (for more than a month). I did everything I could trying to solve this: restart Xcode, clean project, clean build folder, build with a device connected, reinstall Xcode multiple times, even formatting the whole disk and starting from scratch. None of this worked.
During this time my colleague was always able to upload the very same builds to App Store without any problem.
Curiously, what solved this problem for me was disconnecting my non-Apple wireless mouse.
I found this out when I tried to submit an app from my home computer and got the same error. I disconnected the mouse dongle, tried again and it went through.
I've verified this three times both on my home (MacBook Pro 2013) and work computer (Mac Mini 2014).
This leads me to believe that during the app submission process Apple may check if your environment is purely made by Apple or not, and may block your submission based on that. This would explain the "Cannot verify client" message.
This one worked for me:
Delete the Archive that failed during upload.
Clean the solution.
Rebuild the solution.
Archive the it.
Go to Xcode's Organizer, then Validate (this should be 'Successful').
Upload the build.

I can't debug my app because when I run it, Xcode gives me the error:
Process launch failed: timed out trying to launch app
In the device I see a black screen and after the error message the app starts.
How can I fix this?
I tried to change the code signing identity and the provisioning profile, and to refresh the provisioning profiles in the Xcode > Preferences > Accounts > Details tab.
I'm using Xcode Version 6.0.1 (6A317) with an iPad mini, running iOS 8.0 and a MacBook with OSX 10.9.4.
After this, if the iPad goes into sleep mode (the screen turns off) I can't wake it anymore; I have to do a soft reset.
You are using distribution provisioning profile rather than development profile. check this link
How to Fix:
I fix it with:
clean project (Product > Clean)
hard reset device (power button + home button)
delete app from device
close xcode
CLOSE ITUNES (itunes must be closed)
re-open Xcode and run!
I think that iTunes was the problem.
EDIT: 2017/02: Solution still Woks (Thanks to #SalGad for information).
I am using Xcode 6.2, running on iPhone 4 with iOS 7.1.2, the problems happen to me as well.
It turned out that the Project and Targets' Code Signing settings are different from each other! And that's what is causing the issue.
To solve the issue, you must make sure that their Code Signing settings is the same.
One more thing that may be a reason to launch timeout arising is that you have a lot of Provision Profiles on your device. I have about 100 of them, downloaded automatically by XCode from our team dev portal. So if your team have tons of apps and Provision Profiles, you better unlink your XCode from your Apple ID, to prevent automatic downloading for unwanted PPs. It significantly decreases app launching time.
To delete unwanted PPs from your device you have to go XCode - Window - Devices, select your device and click "Show provision profiles..." on the bottom context menu. Then you have to manually remove the profiles. Tip: use key sequences "down arrow" - "backspace", to ease the hand routine.
I had this but nothing previously posted seemed to work. This is what I did to fix the issue in Xcode 6.3.2:
Go to Product->Scheme->Edit Scheme...
Select the Run Scheme
Select the Info tab
Make sure the settings are as follows:
Build Configuration is set to "Debug"
Debug Executable is checked
Launch Automatically is checked
In my case I was using the development profile, but somehow, in Build Settings > Code Signing, the Provisioning Profile for Debug was empty.
But before setting it to "iOS Team Provisioning Profile", I had to reset my account since it said " is Not on Any Development teams"
- Xcode > Preferences > Accounts
- Remove my account (click "-")
- Add the account again
That fixed the problem
Note that if the app still manages to start on the device after Xcode displays this error, you can attach to the running process with Debug->Attach to Process.
This warning is shown when you try to run and debug your code directly in device but you are using distribution profile in your Build Settings.
To directly run the code in device and debug, you need to use development profile in your Build Settings of Xcode.
After setting the development profile, just reboot your device clean your Xcode project and run again.
I hope this helps !!
An app should return from his initialisation procedure in less then 10 seconds, or it will be killed by the OS. This is probably because you are doing too many things in the startup phase.
Try to refactor your code to do it diffrently, by doing lazy initialisation, and only initialize what is really important before showing the first view.
It's hard to give better advice before knowing more about the app itself
I have faced this issue with Xcode 6.2 and Iphone 5s with iOS version 8.3.
I get this message when I deploy the application to the device for the first time.
The work around I found was that with out unintalling the application from the device,redeploy the application from Xcode.It should run perfectly this time.
I observed this only on Xcode 6.2 not on Xcode 6.3 so this might be an Xcode to iOS version compatibility issue.
Big and weird tip for this problem... this was happening to me and none of the advice helped anywhere on the web, but then i noticed if i deleted everything out of the main ViewDidLoad method it would work. I realized there was one line of code that was messing it up. It was a line that was referencing to an array of strings that was way to big. I had something like this NSString *mystring[100][1000][100]; i accidentally added some zeros and for whatever reason this problem produced the same error message that the incorrect signing gives you. So don't let your arrays or matrixes get too out of hand!
Method #1:
Lock your phone, press XCode start, wait till XCode says "unlock your device to launch", then unlock your phone, it will be launched successfully, works every time.
Method #2:
If your goal is just to debug the app, here is another simple and straight-forward approach:
After the app is deployed, launch it manually.
Goto XCode -> Debug -> Attach to Process ... to choose your app from the list, then debug properly.
This works well for me, and it saves lots of time.
I hope this helps, thanks!

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!
