Answer 1

This won't answer your questions but might help people with the same issue. This is Apple bugs you can show here , Nobody can figure out the exact solution for that.

Solution 1: You're confusing SpringBoard and storyboards . Your storyboard is fine but you need to reboot your device (or Quit and restart the Simulator), as the SpringBoard (the process which handles the home screen) has died.

Solution 2: Please remove dispatch_async(dispatch_get_main_queue() statement and uninstall app & clean & build

Solution 3: That error message is just telling you that iOS stopped running. So obviously the app is no longer running and won't be able to again until the iPad finishes rebooting. As far as what causes the crash you need to do some more exploring. Definitely turn on exception breakpoints to see if you can catch the crash before the whole device crashes . Another thing to keep in mind is that the debugger, for whatever reason, will not work if you have distribution profiles installed. If you have an app with an included push profile, for example, it will always crash shortly after launch because the debugger takes it down with it.

Solution 4: What it worked for me was to delete the app in the iPhone simulator, force quit the simulator and hit run again in Xcode .
