I made a slightly altered version of apple's "iPhoneCoreDataRecipes" example:
https://developer.apple.com/library/...ion/Intro.html
I only changed the names of the model classes and the names of some of the attributes, for it to make more sense in the type of app I am making.
When I run the app, though, it crashes on start up, and the debugger window says the following:

terminate called after throwing an instance of 'NSException'
I have been trying to get Core Data to work for months now. I have implemented persistent data with NSCoding, but it is not nearly as nice as what Core Data does - when it is working.
Could someone please tell me what this error means, point me to a good Core Data tutorial, or a good resource on Core Data?
