Password isn't working after app update

If you debug using the same session (you don't close Xcode) password will work, but if you make changes to the code and update the app in other session the layout will display wrong and the password will not work.

I think it has to do with changing the Core Data model, it doesn't match and the password can't be recognized afterwards.
