I cannot build my application anymore since I updated Xcode to the new version (Xcode 5.1). the error message is \'Could not build module \'UIKit\'\'. I have the same probl
In my case it was Could not build module Twitter Kit. In link Binary with libraries some framework reference were showing as red. Deleting and re adding them worked for me.
I had similar issue and fixed it by deleting Xcode from Applications and reinstalling it again.Worked like charm.
I was working on xcode 8 beta and project was building on simulator. But when I tried to run on Device. I got the same error
Could not build module 'UIKit"
It is due to UIKit framwork some how get deleted or Typed something inside it. Deleting Xcode and reinstalling it. Error got solved.
