This looks like XCode is crashing trying to build your application.

Judging by the method names in the traceback, it's looking at dependencies trying to figure out what to build. You might be able to work around the problem by doing a "clean all targets" and trying again.

You might also want to file a bug report at http://developer.apple.com/bugreporter/
