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.

Xcode cannot launch apps on the simulated device “iPhone 6”, as it is currently running an app on “iPhone 4s”. Only one simulated device may be used at a time
This means one of two things:
You have another project window open, and that project is debugging an app using the iPhone 4s simulator;
XCode has gotten confused and thinks you are still debugging something in the simulator, even though you are not. This happens to me pretty often, and I think it's a bug in XCode, in the way it interacts with the simulator.
For #1, go to the other project window(s) and click Stop button to stop debugging.
For #2, quit XCode and start it up again.
I have a piece of software I wrote using xcode 5. Since I upgraded to xcode 6, the app looks strange when I run it on a physical device using the emulator. Not entirely sure what is going on or how I could fix it. It's not respecting the full size of the screen.
I am testing on an iPhone 5s (NOT simulator -- the app looks fine in the iPhone 5s simulator). I am connecting my phone to my comp and running it via xCode.
I am having the same issue with another project I built using xcode 5 and trying to run again in xcode 6...
thoughts anyone?!
Here is a screenshot of what is going on:
I just submitted my app to the app store last week and it got rejected yesterday. The reviewers apparently test on iphone 5S with iOS 7.0.4. They say the app does not load past the intro screen.
I have tested the app on iphone 5 and ipod touch 5th generation, both running the same operating system. On both it works perfectly fine.
Any ideas what could be the problem? It's a bit of an issue that I cannot test myself as the app uses the camera in the first screen and that's why immediately crashes when running in the simulator... but if I uncomment the camera setup it works in 64bit simulator...
edit:
I am using C4 for most of my interface elements. So camera init looks like this
cam = [C4Camera cameraWithFrame:CGRectMake(0,0, self.canvas.width, self.canvas.height)];
cam.cameraPosition = CAMERABACK;
[self.canvas addCamera:cam];
[cam initCapture];
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.
Is it normal that when i try to test my app it crashes on launch?
I explain.
I have my app that works fine in the simulator. I wanted to try to test it on my iPod Touch 4g.
I built and run from XCode, and that's what happened: the app launches fine (it shows me a black splash screen),but then suddenly it comes back to the springboard,with no reason.
If i open up the app manually,after it crashed,it works without any problems. It happens only one time,just when i build and run,and i don't know why.
How can i do to avoid this? On simulator it works with any crashes,but when i run it over my iPod,it crashes.
Program ended with exit code: 0 // on simulator
The app is likely to be failing to run on the device as xcode is trying to attach the debugger to it but doesn't have permission to do so.
Check your entitlements.plist within your project; you probably have one that has get-task-allow set to NO. This needs to be 'YES' to allow the debugger to attach. (It does need to be 'NO' for adhoc builds though - one solution is to exclude the entitlements.plist file from the debug build.)
