xcode build error for cardboard VR

I have version 7.3 beta of xcode and 5.3 of unity. I have built a simple terrain in unity and added the cardboardmain prefab to the scene and followed all of the build instructions on the google’s developer site. However, i keep getting a a ton of errors when I try to run the project in xcode, and I can’t figure it out for the life of me. Please help!

Hello? Can someone please help me with this?
