I am trying to launch my app on device. It is launching successfully on the simulator.
List item
I use 7.1 SDK
Xcode 5
And the device is a 7.1 iPhone 4S
I have tried:
Clean
Clean Build Folder
Deleting app
Disconnecting/Reconnecting device
Booting device
restarting Xcode
What can I do to make it work?
Could it be something with Code Signing?
Currently i have it set to 'Dont Code Sign'
I had this problem when I used a Distribution certificate instead of Developer one when running the app from Xcode. You may check it out your target --> Build Settings --> Code signing.
As #AndyDynn pointed out in his comment:
Make sure you do this on the "Target" build settings and not just the "Project" build settings.
I literally restarted my iPad, that was connected for testing the app, and that resolved the issue.
To run your app on a device, you will perform these tasks that follow:
Request a development certificate.
Add your device to the portal.
Code sign your app.
Launch your app on the device.
For more detail check this
If your provisioning profile and code sign everything is alright then try once Quit and Restart your XCode. It will work for me.
I just had this issue.
I had to open the app on device and tap Trust Computer.
No need for me to reboot everything 20 times, yay.
Below are 2 awesome hacks that have not been mentioned yet:
HACK #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.
HACK #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!
I got the same problem and after looking at the answers here I found mine. The issue at hand was: my dev distribution certificate was gone from iOS Dev Center, so I just assume it had timed out. I didn't get a nice warning though, just the above error - installing worked but debugging didn't. So I had Xcode regenerate a new one for me.
One more thing to try if you've tried the above:
i found this link about quitting itunes to avoid the timeout. This works for me with xcode 5.1
In my case there was no value at Targets -> Build Settins ->Provisioning Profile. Though Code Signing looked ok)
I cleaned out my provisional profiles, rebooted the iPhone, rebooted the computer, and it worked for me.
Just to throw out an additional suggestion to anyone coming across this problem (it's been burning me frequently lately) -- try going to the Targets -> (Your Target) -> General -> Team and re-selecting the same Team, which forces Xcode to update profiles for you.
That has been the culprit for me a couple of times. Seems to happen specifically if you've recently re-downloaded a distribution certificate for new devices or w/e. Or if you've just dumped your Provisioning Profiles directory in general.
I had the same problem and I tried all the suggested steps but I managed to get it deployed and run only after I powered off my iphone.
Checked my Targets and code signing details, didn't help. I did three things:
Clean Build Folder
Close Xcode and delete everything in Derived Data
Rebooted my device
Everything worked fine after that. I had changed some App Transport Security setting in my info.plist right before this occurred. Not sure if it is related or if only one of my 3 steps were necessary, but it worked.
Make sure the Provisioning Profile setting in your environment is set to your development profile: Project > Build Settings > Code Signing
Consider setting it in your Target settings and the Pod project (in case using Cocoa Pods).
In case the development profile is not present create or download it:
Certificates, Identifiers & Profiles > Provisioning Profiles
After following the above, it still didn't work (from xCode 6). But after rebooting the phone and deleting the app, it worked.
Check Product Name for dots "."
"." are not allowed in Product name.
Selection in provisioning profiles may cause this problem. So while launching an app on to the device, make sure you are using the development profile & not the distribution profile. I have been facing the same issue. But got away with it using the same process.
Check for Project > Build Settings > Provisioning profile & select your development profile.
And also take care of Code Signing Identity in the same tab. Make sure you choose both the identities of Developer & NOT of Distribution.
Below two steps solved for me:
For xcode version: 7.2
1.Select any of your simulator to run ( just start your run, no need to load the app completely).
2.Stop it.
3.Then select your device and run.
This solved in my case.
option + command + shift + k and then run the project did the trick for me.
If your goal is to just launch the app and debug it, you can also edit the schema to "Wait for executable to be launched" and run the app manually.
The setting is under Edit schema > Run > Info > Launch. Choose "Wait for executable to be launched" instead of "Automatically". It will wait for you to run the app (by manually tapping it) instead of timing out.
As all of the above answers didn't helped for me I'll publish my solution:
Deleting all the occurrences of xcuserdata folders in .xcodeproj and .xcworkspace and restarting Xcode fixed the problem. To delete it right click your_app_name.xcodeproj and/or your_app_name.xcworkspace in your app folder and select "Show Package Contents". I hope that help someone to save some time.
Just restart my Device and works everything fine
I tried:
Restart the device (iPhone)
Clean build the XCode project
Then it works.
Check whether the device memory is full.
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.

Just restart my Device and works everything fine
I tried:
Restart the device (iPhone)
Clean build the XCode project
Then it works.
Check whether the device memory is full.
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.
I receive the following error when trying to run the app on my device.
error: failed to launch '/Users/michael/Library/Developer/Xcode/DerivedData/Build/Products/Debug-iphoneos/Word Processor.app/Word Processor' -- No such file or directory (/Users/michael/Library/Developer/Xcode/DerivedData/Build/Products/Debug-iphoneos/Word Processor.app/Word Processor)
The app runs fine in the simulator. When I try to debug on the device, it appears to copy the app (I can see the icon), but then stalls with the above message. Xcode says it is running the app on my iPod, but nothing is happening on my iPod.
When I click on the app, the app appears to launch, but seems to be missing resources.
Other projects of mine work properly. What setting do I need to change to make this work properly.? Looking at the error message, it seems to be looking in my mac for the app. But this doesn't make sense since I am trying to run it on my 4th gen iPod touch. I am using Xcode 4.3.1 and iOS 5.1
With Mountain Lion and the latest version of Xcode (4.4.4F250), none of the suggestions in this thread worked directly (clean, clean project, remove derived data folder, etc). This sequence did. From DhilipSiva:
Disconnect your device
Delete the app from your device
Quit Xcode (Don't just simply close the window, quit it)
Delete derived data folder rm -fr ~/Library/Developer/Xcode/DerivedData (console)
Start Xcode,connect device & run the project
I solve this by going to Targets-> Info -> Required Device capabilities and delete the option with armv7.
Hope this helps!
This is a recurring problem that many developers are having with the current version of Xcode. The temporary workaround has been consistently deleting the DerivedData folder.
You can add doing it to a build script or even make it a cron job:
rm -rf ~/Library/Developer/Xcode/DerivedData
Sad, but true.
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 also had this problem after changing from a lower XCode and iOS version to the current XCode and iOS version.
I fixed this problem by changing th iOS Depolyment Target to a lower version, since my Device is not updated to the latest iOS yet.
You can do this by clicking the project inside the Info tab.
Have you looked at the Developer Certs and Distribution Certs if you have. When running in debug mode from Xcode your will need your app assigned with the developer cert and not the distribution cert. The distribution certs do not allow for debugging.
This error will manifest whenever the device capabilities described in the Info.plist do not match those of the device.
In my case, I was requesting GPS support and location-services support and trying to test on an iPod touch.
I struggled with this problem for 2 days and went through all the posts, tried all the options including, restarting Xcode, device, deleting DerivedData folder etc.
Finally, the problem was with the Info.plist file. In my case, I had improper icon paths in the Info.plist file. I suggest you to archive the application and then validate it to get the exact problem in you case. Only when I did that, I was able to find the issue.
I solved this problem many times with DhilipSiva's solution. However, it may not work sometimes. If that is the case, consider deleting and re-adding the target.
Removed armv6 support and it started working again
I stumbled upon this same problem on several diferent projects, researched a lot on forums and even here on Stack overflow. A lot of solutions were given, and some people seemed to get them working, but none of them worked for me.
So we tried some pretty obvious course of action, which for some reason we didn't tought about before: I've done a CHMOD -R 777 on the EXACT path indicated by the error message (I copied it directly).
Worked like a charm, 100% times!
Hope it helps, guys!
As Chronos mentiod, the device capabilities might be the reason. In addition I would say that in my case it was all about the UIRequiresPersistentWiFi key, which (for some unclear reason) didn't let me to install my app on an iPhone4. Hope this helps ones who tried everything else and haven't fixed the problem yet.
I solve this by going to Targets-> Info -> Required Device capabilities and check id at 0 index if armv7 not in 0 index then remove other things and armv7 set on 0 index and clean app connect device and run.
Hope this helps fine!
I did these steps:
Delete derived data: rm -rf ~/Library/Developer/Xcode/DerivedData
Deep cleaned the project: Shift Key + Option Key + Command Key + letter K key
Quit the project
Quit XCode
Deleted the app from my device
When I reopened the Xcode, launched the project, and then launched the app it successively ran on my device
For me it was Command Line Tools
Go to Xcode -> Preferences -> Locations -> Command Line Tools
Make sure you select latest Xcode version. I selected Xcode 11.0, and everything started working.
I get the similar question and has searched via the internet the whole day without solution yet...
Xcode 12, iOS 14.
I'm using a cocoaPods call GCDWebServer, which will open a build-in http service in iOS. Now it works fine in simulator and I could open a home page of it in my Mac's browser. But I cannot open the home page if running it with real iPhone. The browser said "Cannot connect to server"
And in console, everything is same without any errors provided for me.
Thus, how could I debug this?
[DEBUG] Did open IPv4 listening socket 3
[DEBUG] Did open IPv6 listening socket 4
[INFO] GCDWebUploader started on port 80 and reachable at http://192.168.1.3/
