I have tried deleting derived data and Clean and Build and restarting Xcode. No deals :(.

Weird thing. I tried adding the
-fno-objc-arcflag to some Facebook files and the project finally built. I guess the lesson here is that when Xcode generates these types of errors, the source of the problem may be in another file. This may especially be true if Xcode is complaining about a file that you have already flagged!Hopefully this will be of help to somebody :).
