How to delete an old/unused Data Model Version in Xcode

Question

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 develop

Answer 1

I've just found the need to do this. I created a new model version then realised I didn't need it after all. I was surprised to find there was no way of deleting it (that I could find) from Xcode. Still, to remove it I did the following:

First I made sure it wasn't my current model version. Then I went to Finder and found my *.xcdatamodeld file. Right click and Show Package Contents on that. In there you will find the actual model file and can delete it.

This still doesn't remove it from Xcode and it will show red in the Files and Groups. To stop this from happening go back to Finder and Show Package Contents on your main *.xcodeproj file (you may want to make sure you have a backup of this first). In there open up and edit project.pbxproj do a find on your model version name, in my case "interval 8". For me it appeared on two separate lines. I removed these lines and now it's completely removed from Xcode.
