Core Data Mapping Model Not Showing Up
===

I've been moving a project from Xcode 3 to Xcode 4.3.2 and when I add the .xcdatamodeld directory to the new project it does not show the .xcmappingmodel directory.

It does show the .xcdatamodel directories. I have three versions of the data model since I started the app (it's in the app store).  I also preformed a custom migration along the way and so that is what the .xcmappingmodel is for with its own custom class for one special object migration.

Any idea why Xcode 4 does not display the .xcmappingmodel directory? It needs to be included and built with the project in case someone still has the older version.  I also thought mapping models are still part of Core Data.
