No visible @interface... ?

I'm working on the diary app to get a handle on Core Data. Sadly I keep running into problems. Right now, I'm getting an error that I don't really understand. In AppDelegate.m's applicationWillTerminate method there's a method that says [self saveContext].

After I moved all the core data methods like Ash says in the video, this method gives an error that says "No visible @interface for 'AppDelegate' declares the selector 'saveContext'".

What does this mean?

Ok - I resolved this error by putting the applicationWillTerminate method in the CoreDataStack.m file and importing AppDelegate.h. Is this a good way of handling this error or did I miss something?
