I have a project and I am using core data.
I have some entities, with attributes. When I started the project I choose some atributes and now I want to change their types (Int to String for example). ANd so I did it.
THe thing is, I am getting errors...
I checked the code, I think every thing is ok.
I even deleted the entire entity and made a new one with some name but it doesn't work.
How can I change it with success?
