My thoughts, my projects, my dreams...

Note: This article talks about the Core Data (via Magical Record) so I’m assuming that you are already familiar with it or at least you know the basics. If this it is not the case you can find very good tutorials on the Tim Roadely’s blog or on the Ray Wenderlich’s blog.
