Answer 1

I just removed the library and its references. Cleaned the project, again added the required libraries and checked all references and linking, Build and run the project.

It worked!

Answer 2

The "clang: error: linker command failed with exit code 1" usually occurs when you accidentally added(import) the implementation file(.m) in place of the header(.h) file.

Check and confirm if EditProfileViewController.m is not imported.

Answer 3

The error indicates that /Users/Admin/Desktop/Radius/Radius/Radius/AssetsLibrary.framework/AssetsLibrary is missing an x86_64 simulator slice.

Assuming you built that framework yourself, update it with i386 and x86_64 simulator slices (build for i386 and x86_64 and then lipo the resulting slices into the universal framework).

If you got it from a 3rd party, contact them for a version of the framework that has all the appropriate slices.
