title: Create NSManagedObject subclass file in Xcode 3.2.2
body: <p>I am just learning Core Data on iPhone and the <a href="http://iphoneinaction.manning.com/iphone_in_action/2009/08/core-data-part-2-the-data-model.html" rel="nofollow noreferrer">tutorial</a> I am following says to create a new file and select <code>NSManagedObject</code> as the template. However, in Xcode 3.2.2 it seems to be gone.  Is there any way to get it back or some kind of workaround?</p>
  
  <p>Thanks in advance!</p>
