I tried to delete the com.apple.dt.Xcode.plist & reinstall Xcode but it keeps crashing on devices, On simulator it works.

Help please.

Answer 1

Try to exit fullscreen mode in Xcode and run your app again. It was crashing for me when Xcode was in fullscreen mode.

This is Xcode 6.0 with OS X Yosemite.

Answer 2

The solution for me was to remove Urdu language from the list (System preferences>Language and Region). It was set as primary. I kept only English and after restarting Xcode is not crashing anymore.
