title: xcode 5.1 keeps modifying my storyboard
body: <p>I've got an odd problem here. Whenever I <strong>view</strong> my storyboard file in Xcode, it immediately gets "dirtied" and needs to be saved. I save it. A second or two later, I see that the icon has gotten dark-gray again, indicating a file change. </p>
  
  <p>The weird thing, is that it only happens on a single storyboard in a specific project. I can open up other projects, and it's fine. The only way to push to git, is to quit Xcode, and then do the commit/push. And the funny thing is, when my colleague opens the project, he gets the same problem on his computer.</p>
  
  <p>If anyone has seen this, I'd love to know your solution.</p>
  
  <p>Thanks.</p>
