title: Deleting or renaming model version in XCode 7
body: <p>I can't seem to find any way to delete or rename a Core Data version. It is not the current model version. Once you add a version, if you right-click it 'delete' is disabled. You also can't click it a second time to rename. I can delete the version in the package by opening it in Finder, but then it still stays there as deleted. I suspect I will have to edit the project file using Text Edit.</p>
  
  <p>Is there a cleaner way to delete an unwanted Core Data version in XCode 7?</p>
