I'm working through the slightly outdated core data tutorial in Xcode, (NSPersistentDocument Core Data Tutorial: The Employee Class - Developer Documentation) and it's asking me to select a managed object class that is supposed to have these special options. I already know from a previous screenshot that this document hasn't been updated since the iphone SDK's, my select file interface layout is different. But apparently they also took out managed object classes, so I don't know what to do. I looked everywhere... Anyone know either how to make one, or how to get around it?
