What is the name of the source file that is generating that error message? — Droppy, Jun 13 '16 at 13:06
@Droppy Error message come from UIKit and Foundation Framework not from classes. — Rushabh, Jun 13 '16 at 13:33
Yes, but it was generated during the compilation of a file, no? — Droppy, Jun 13 '16 at 13:34

Try to move your `#import`s from .h files into .m files as much as you can. — Nicolas Miari, Jun 21 '16 at 07:25

Maybe you can break the cyclic import by #import one in the .m file,or you can learn to use @import the new feature which use the module map made dependency.

This might generalise your situation - You have imported class B into class A and now you are importing class A in class B, so in second case rather than importing class A in B use forward declaration - Use @class A in class B (second case). If you are using .pch file, you might be adding Framework or Headers twice. In .pch file and in other files as well. In your case try removing the UIKit and Foundation frameworks either from .pch file or from other place where you are adding them repetitively.
