Question

Could not build module UIKit

I tries a lot but couldn't solve it.

Answer 1

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

You have 2 solutions:

1. Just Re-install XCode.

OR

2. Copy the Framework from another Mac (with same XCode version) & paste into yours.
