title: Workspace created by Cocoapods won't open
body: <p>I have an existing project that was working just a few weeks ago. I recently tried to open the workspace that cocoa pods created and it just spins on "loading" forever in Xcode 6.3. I deleted the project file and ran pod install to create a new one and got the exact same result. </p>
  
  <p>Anyone else running into this? Ideas?</p>
