title: Xcode documentation doesn't work offline despite downloads
body: <p>I've been trying to download the SDK documentation for offline reading so that I can reference information with no Internet connection, however Xcode seems to not care that I've downloaded the docs and will only display information if I have an Internet connection. By this I mean I can see the tree on the left pane of the Documentation Viewer but clicking on anything will not load the page unless there is an Internet connection. If I turn my Wi-Fi back on, it immediately works again.</p>
  
  <p>This is occuring on Xcode 5, 6 and 6 beta 4 despite downloading the iOS 8 (for 6+) documentation or any documentation for that matter from the Preferences pane.</p>
  
  <p>Removing the docsets manually, rebooting and then re-downloading them, did not resolve the matter.</p>
  
  <p>Removing the .plist files also did not resolve the matter.
   com.apple.dt.Xcode.plist
   com.apple.dt.Xcode.LSSharedFileList.plist</p>
  
  <p>This is happening across all 3 versions of Xcode I have installed so I'm not sure if its deeper than just 1 version.</p>
  
  <p>Is there perhaps another file that says whether it has been downloaded or not that I can clear and re-generate? Or is there perhaps an underlying permissions issue on the docsets?
  In Xcode, is there a command line version of loading the app so I can see any error messages?</p>
  
  <p>I have downloaded Dash (<a href="http://kapeli.com/dash">http://kapeli.com/dash</a>) and this immediately picked up the docsets I had downloaded and made them available offline. While I can happily use this now, It would be nice to have the integration with Xcode.</p>
