title: React Native run-ios build fail after xcode update to 8.0.
body: <p>Okay so I've been working on this React Native project for a few weeks now without any issue. I recently updated to xCode 8.0 and RN build is failing. When I do "react-native run-ios", it returns a "BUILD FAILED" error. I tried it through xCode and it returns something similar. I tried looking around but I can't seem to find a solution to this. I'm sure it's probably some setting that changed within xcode that's messing it all up. </p>
