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.

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