title: updated iOS 6.1.2 now I can't archive app xcode
body: <p>When I want to distribute my app from XCode I select my device in the list at the top and that enables the option to Archive my application.  </p>
  
  <p>I upgraded to iOS 6.1.2 last night and now my device will not show up in the drop down list at the top so I can't archive the app.</p>
  
  <p>How do I fix this?</p>
