break

}
Error: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'NSFetchRequest could not locate an NSEntityDescription for entity name 'IngredientsList''
Anyone, any idea?
EDIT
Did you create an entity in the data modeling tool in Xcode and then set its class to "IngredientsList"? In the right-hand Utilities pane, it should look something like this:
