I get this warning for my xdatamodeld file: “Version hash information not available for all models”. How do I get rid of this? I’ve also started to get a crash at startup when I install the app as new … wonder if they’re related? This is the crash:
* Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘Cannot create an NSPersistentStoreCoordinator with a nil model’
This is a iOS5 beta issue, caused by having a fetch request in your model file. For now, removing the fetch request fixes it.
