momcom: Experimental Core Data Model Compiler
Tom Harrington introduces momcom (the counterpart to momdec):
After writing momdec I realized I could probably compile models as well as decompile them. So, I wrote some code to do so. Twitter comments by John “Wolf” Rentzsch about how hard it might be may have spurred me on a bit. The code also fixes a bug I found in Xcode’s model compiler (rdar://problem/13677527 and http://openradar.appspot.com/radar?id=2948402).
