100+ warnings in new Xcode 7.1?

I have updated the latest version of Xcode 7.1. I am getting around 100+ compiler warnings.

Example:

Answer 1

To delete the derived data, Alt-Click on "Go" in the Finder top bar. Then select "Library", navigate to Developer/Xcode/DerivedData and delete the entire folder.
