Question

Suddenly it stops building application in device. In simulator its working but when I connect the device and try to run it in device it gives me an error:

Answer 1

I accidentally edited the Foundation framework file so UIKit.framework got corrupted. The only solution is recover the original.

You have two solutions: Just reinstall XCode or copy the Framework from another machine with the same XCode version and paste into yours.
