问题
I deleted UIKit.framework and Foundation.framework in an xcode project by accident. I can't find the framework in the target information (general tab) link libraries section.
How could I add them to the project again as I'm now getting many errors!

Project > Edit Active Target > General tab, click the + button to add frameworks.
