Don't fight the with Xcode on this unless you really need to alter your generated properties, doing so will just leave you frustrated.

Think of the auto-generated class as any other class in your application. If you need to add functionality to your managed object class, simply change your class definition into an extension and extend your object.

change your class:

class MyManagedObject : NSManagedObject { /* implementation*/ }

to an extension:

extension MyManagedObject { /* implementation */ }
