Adding Core Data to existing project in XCode 4

Question

I started off the project without Core Data and now I would like to add that functionality to my apps. How do I do this?

What additional things does XCode sets up when

Answer 1

I've found the easiest way was to create a new project, with core data, delete the files in the project and drag and drop from the non-core data project to the core data project. (Main.storyboard, AppDelegate, ViewController, etc)
