title: Xcode changing my xib when opening another file
body: <p>This is what is happening:</p>
  
  <p>I Have a NSTableView in a xib that uses a custom view for cells. This works fine if I press run when the xib is open.</p>
  
  <p>However, when I leave the xib and run with any other file open the XCode changes my xib. I have commited the working xib, changed file and this is what xcode is changing:</p>
  
  <pre><code> &lt;imageView horizontalHuggingPriority="251" 
              verticalHuggingPriority="251" 
              id="Ciy-iY-YFr"&gt;
  
  [REMOVED]&lt;rect key="frame" x="20" y="5" width="50" height="50"/&gt;
  [ADDED]&lt;rect key="frame" x="20" y="-56" width="50" height="50"/&gt;
  </code></pre>
  
  <p>Basicly it changes my imageView that is inside the cell. I have tried to remove auto-layout, create again the tableView and nothing worked so far :/.</p>
  
  <p>This is happening on XCode 5.0.3 on OSX 10.8.</p>
