A utility that makes it easy to create and generate custom Core Data managed object classes. Mogenerator manages two classes for each entity in your Core Data model: one for the code generated by Xcode, and the other for your custom logic. Mogenerator combines the two classes so you can regenerate the Xcode class without being worried about overwriting your custom logic. There is also a tool called Xmo'd that seamlessly integrates mogenerator into Xcode.
