IB file has reference to wrong project?


I have no clue how this is happening, but when I try to run the Hypnosister code I’m getting this error from the debugger:

2011-05-05 15:41:11.525 Hypnosister[13779:207] Unknown class WhereamiAppDelegate in Interface Builder file. 2011-05-05 15:41:11.529 Hypnosister[13779:207] *** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: '*** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (MKMapView)' *** Call stack at first throw:

So it’s looking for the class from a different project in my current xib? I’ve not done anything at all to the xib in this project, but if I look at it the delegate is the HypnosisterAppDelegate.

Any clue what’s going on?
