mogenerator

Visit the project’s pretty homepage.

Here’s mogenerator’s elevator pitch:

mogenerator is a command-line tool that, given an .xcdatamodel file, will generate two classes per entity. The first class, _MyEntity, is intended solely for machine consumption and will be continuously overwritten to stay in sync with your data model. The second class, MyEntity, subclasses _MyEntity, won’t ever be overwritten and is a great place to put your custom logic.
