How can I delete an old Data Model in Xcode? The option is disabled on the menu. (The models I want to delete have not been released to the public - they are interim development models.)

It's a hack, but this worked for me:

  1. Set the Current version of the model in Xcode to one that you want to keep
  2. Remove the .xcdatamodeld from your project (Right-click -> Delete -> Remove Reference Only)
  3. Show the contents of the .xcdatamodeld package in the Finder (Right-click -> Show Package Contents)
  4. Delete the .xcdatamodel file(s) that you don't want anymore
  5. Re-add the .xcdatamodeld file to your project

This eliminates the need to manually modify any of the project metadata files.
