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:

Could not build module UIKit

I tries a lot but couldn't solve it.

Answer 1

I tried with delete derived data,delete application from project list but when i delete xcode and install new one its working so its best way just delete xcode and install new xcode.

Answer 2

For some reason your UIKit.framework is corrupted, either copy a working UIKit.framework from somewhere else into

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/System/Library/Frameworks

Or reinstall Xcode the fix the issue.

Answer 3

It worked for me after remove all folders in DerivedData folder.

Answer 4

Cleaning the project and restart xCode worked for me.

Answer 5

Suppose you have changed or deleted anything in the UIKit framework, then shows this error.

If you are able to find that class or .h file to be changed or deleted, then replace that whole file content in that .h file from other system's Xcode (confirm that should be similar Xcode version).

For example, In UIView.h file - I have deleted a method and closed and opened the Xcode. Then I couldn't reverted that code.

Answer 6

Something that might help would be to set the Derived Data location to "Relative" in XCode preferences, then Clean & Build
