Unity 4.7 & Xcode -- lots of errors on a project that had none 2 months ago...

Hello! I'm unfamiliar with how to use Xcode aside from building the game to the iPad and pushing it to the store. I'm getting 201 errors when I try to build the latest version of my game -- the only changes were a new version of Unity (4.7) and a new Xcode (May 2016), and some new audio files.

Any idea what I could be doing wrong? These errors don't make any sense to me unfortunately.
