Question

I am working on an iPhone app.
I have modified my data model in Core Data by adding an entity.
And now my app crashes.

I think that when doing that (changing the model) I have to remove some files and reset the data store so that things can work with my new model. But I just can’t remember what exactly I need to do.

Thanks for any tip.
