title: Automatically created NSManagedObject subclasses don't use ARC
body: <p>My project is ARC enabled (the build settings have Objective-C Reference Counting set to YES). There are no file exceptions to this, it is enabled project wide. (Latest stable version of Xcode).</p>
  
  <p>When I create an NSManagedObject subclass via File > New for a Core Data entity, the generated header uses the following in its property declarations:</p>
  
  <pre><code>@property (nonatomic, retain)
  </code></pre>
  
  <p>But 'retain' is not ARC!! Is this a bug, or is there something I'm missing or not understanding? There are no build warnings - if this is a bug though, how can I remedy it?</p>
