I have an app that i am release as iPhone and iPad even if it developed as Universal. The reason is that i have release an English version that is Universal and just want to update the iPhone and iPad Swedish versions as it have been with separate apps for the different devices.
When i run on the iPhone device i have no problems but when testing with iPad i get the message below, which i do not know how to remove:
"Could not launch “FamilyQuiz_3"
No such file or directory (/Users/peterk/Library/Developer/Xcode/DerivedData/MyApp_3-fosmfwberzyfryenqrjlfpacftjv/Build/Products/Debug-iphoneos/MyApp_3.app/MyApp_3)
I can start the app from the iPad device but it do not start automatically when submit from XCODE.
1)make sure your iOS Deployment Target version is the same or lower than the one on your device in build settings.
2)delete it from the device
3)close xcode
4)Goto /Users/peterk/Library/Developer/Xcode/DerivedData/ on your computer and delete the
MyApp_3-fosmfwberzyfryenqrjlfpacftjv folder
if that still doesnt work go and try deleting the app restarting your phone, and then restarting your computer even, and doing it again.

When I first run my project from Xcode in iOS physical device, it work fine. But if I stop the project from Xcode and again start the application from the device, it shows the Splash screen and than quit. I don't understand what is going wrong on the second time.
In both of the cases I am on the same network.
I have curious problem. I have written my own android application, which getting some notifications from desktop CRM system through GCM. I tested it on two cell phones:
1- LG D320 with Android 4.4
2- Sony Xperia SP with Android 4.3
Problem is, that notification is comming only other devices then in Sony Xperia. I tried to download apk file of project to third device (I think that is also android 4.3) and notifications running without any problems.
Do you have any tips, what I should check on my device or in project? Thank you very much
PS: I have written android project in VS 2012, c# with Xamarin plugin.
I have a news in my case. I rebuilt APK file again, installed it and notifications working properly. But... I have two computers to deploying android applications. If I build APK installation file in first and then install it on cell phone, I cant deploy application properly from second PC to the same cell phone. Notifications stop working.
Now I know why notifications are not working and it is important!
Eventhough, Xcode 6 displays in iOS devices section my iOS 8.0.2 running iPad2 wirelessly and builds normally my app, when it tries to run end up the the following message:
Cannot retrieve value from the passcode locked device.
Please check your setup and try again. (0xE8000016).
Any ideas ?
Try restarting the device to make sure Xcode is referencing the correct device.
In my case, Xcode detected one of my iPads nearby as a wireless device (which happened to be passcode locked), but when I plugged in my other iPad it mistook it for the wireless one.
Using Xcode 5.1 to debug an iOS 7.1 iPad application.
When I build and run my project in the iOS Simulator, the simulator opens and my app icon pops up for a second. Then it looks like the app stops installing and the simulator goes to the home screen. Xcode still thinks it's debugging and it doesn't show any errors in Xcode or the simulator. I can go to my app in the simulator and click it again, but it just crashes. I get the same behavior in iPad, iPad Retina, and iPad Retina (64 bit). Any subsequent tries to run the app in the simulator doesn't even attempt to pop the app icon up until I quit the iOS Simulator and try again. All the usual fixes haven't worked for me yet.
Fixes I've Tried:
1. iOS Simulator > Reset Content and Settings...
2. Window(in Xcode) > Organizer > Delete Derived Data & Delete Snapshots
3. Delete Contents in ~/Library/Application Support/iPhone Simulator
4. Uninstall Xcode and reinstall
5. Clean project and rebuild
6. Restart machine
I'm out of ideas. Is there something I've missed?
Thanks all!
Create another app with the exact same template and look at the app delegates and make sure they are the same.
Example: AppDelegate.h and AppDelegate.m
You might've accidentally deleted an area that helps load the App.
Alright I found the problem. I was playing with how we load our frameworks because we were having other issues before and I left a bad value in our Linking settings.
Here's how I fixed it:
Project > Build Settings > Linking > Mach-O Type set to "Executable"
It was set to "Bundles" before which causes Xcode to package the app in a way that caused ours to break.
Helpful Post: In Xcode project target build settings, What is Mach-O Type?
I am using XCode 5, with an iPhone 5s as the dev device. Every other time I run the app I get a pop that says "Could not launch [app name] \n busy". My iPhone 5s then appears to crash and the only way it will respond is if I hold the home and lock button until it resets.
The application is a single view application, the only thing I have done is added the Parse.framework from here and used
[Parse setApplicationID:appID clientKey:clientKey];
[PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];
In applicationDidFinishLaunchingWithOptions, along with some UI that isn't hooked up to anything.
I'm not sure if this has to do with Parse or possibly the App settings.
So to be clear, the behavior is:
Fresh reset > Build and Run application on iPhone 5s > application runs fine > Build and Run application on iPhone 5s > application appears to launch but screen remains black and iPhone is no longer responsive except the screen will turn off when the lock button is pressed (but not back on) > Build and Run application on iPhone 5s > XCode says "could not launch app - busy" > hard reset iPhone
When I run this on the 64-bit simulator it works fine.
Edit 1:
I have tested with multiple applications now that we know work on multiple other devices (iPhone 5, iPhone 4, iPhone 4s) and the simulators. I don't have another iPhone 5s so it is hard to compare exactly but everything crashes my 5s..
My device was completely stuck with black screen. "To fix you have to hard reboot, holding the power and home button until the phone reboots - doesn't lose any of the data you have on your phone (a concern the first time I did it)." as stated here:

For iPhone7 there is a different approach:
Press and hold down the power button located on the right side of
the iPhone 7.
While holding down the power button, press and hold
down the Volume Down button on the left side of the iPhone 7.

You were using your phone when you ran the app. Make sure you don't use your phone after you press build and run, otherwise it will be "busy"
Which Xcode version do you use? Same issue with Xcode 5.0.1 + iPhone 5S (iOS 7.0.4). It crashed my iPhone 5S even by the simple application created by Xcode's default project template.
It seems this issue has been fixed in Xcode 5.0.2. Xcode 5.0.2 works fine for me by now.
I've got the same problem for several times. It seems that this problem always happens when iCloud or other background App is running & the App I was debug is already in running mode.
My suggestion is: Avoid any background App running when debug and Make sure the App debugging is fully killed before restart a debug.
It is obvious a bug in iOS 7 + Xcode 5.
I had the same issue and upgrading to Xcode 5.0.2 resolved it.
