Cannot create an NSPersistentStoreCoordinator with a nil model

Question

Been having my first crack at Core Data and I\'m getting the following error when running my code on my device, but it works fine on the simulator..

Answer 1

What's probably happened is that your xcdatamodeld file from Apple's source code has turned into a xcdatamodel(without the d) file and therefore they aren't considered the same.

The quickest way to fix this, is to select the xcdatamodel file in your project navigator and in to the menu bar

Editor->Add Model Version...

and add a new version of your model. Make all changes to the new version.

This works in Xcode 5
