Shog9's edit to this question specified that the version of Xcode being used was Xcode 5. This wasn't previously detailed in the question, and as a result, this answer (which basically consists of "Upgrade to Xcode 5") had been rendered nonsensical.
The question is probably more useful in its current form, but if we're going to keep it that way, the now-irrelevant answer should probably be nuked.
I'm not sure whether Shog9 put in the version number to match the accepted answer, whether he put it in by error, or whether there were (now-deleted) comments by the question asker stating that he was using Xcode 5.
I wasn't sure whether the appropriate course of action was, so I thought I'd make a Meta post and see what others made of it.
