title: Auto property synthesize will not synthesize property - new warning iOS8.3
body: <p>After updating to iOS8.3 I started getting a bunch of new warnings that werent there on iOS8.2. One in particular that caught my eye;</p>
  
  <pre><code>@property (strong, nonatomic) IBOutlet UITableView *tableView;
  </code></pre>
  
  <p>which was declared in a '.m' file.</p>
  
  <p>What has changed in iOS8.3 to make this a warning? </p>
  
  <pre><code>Auto property synthesis will not synthesize property 'tableView'; it will be implemented by its superclass, use @dynamic to acknowledge intention
  </code></pre>
