Xcode Data Model Compiler - MOMC Error: Command momc failed with exit code 1

I am having troubles integrating XMPP on my iOS Project using Xcode 4.4 under Mac Mountain Lion OS X. I followed every step but I got stuck with this problem:

Command momc failed with exit code 1

See screenshot:

I have deleted all the .xcdatamodel files, clean and re-build the project, but the error is still there.

This also can happen when the project is first compiled on a newer version of xCode (beta versions for example) and then trying to recompile with the original version.

Check if you have empty .xcdatamodel folders inside .xcdatamodeld. This may happen due to git behaviour for example.

Maybe the problem is iOS/iOS Simulator version! If you don't delete the *.xcdatamodel for git, you can try replace iOS/iOS Simulator SDK or update. My problem is resolved in this way.

Ok. Solved it. You have to delete the *.xcdatamodel files on the Xcode project. (Right click > Delete).
