How to Turn xcdatamodel file into xcdatamodeld file?

objective-c, xcdatamodel, xcode

Solution

My answer from How to create the magic .xcdatamodeld folder / package?:

To create a model bundle you select the single model, open the `Editor` menu in the main menu and select `Add Model Version…`.

Problem

I still have an xcdatamodel file. However, when I created a new project, xcode generate an xcdatamodeld file (with a d). I want to convert my xcdatamodel file into xcdatamodeld file. I know that xcdatamodeld is some form of directory. How would I do that? I can't copy the entity to the xcdatamodeld file
