So I have CustomEntity1 and CustomEntity2 generated with mogenerator. CustomEntity1 have a to-many relashionship with CustomEntity2 and CustomEntity2 have a reverse relashionship to-one with CustomEntity1.

My question is when I add some CustomEntity2 to CustomEntity1 by doing :

[CustomEntity1 addCustomEntity2Object:entity2FreshlyCreated]

Does it set the inverse relashionship ? Or do I have to do this too ?

CustomEntity2.parent = CustomEntity1;

    The whole reason Core Data asks you to indicate an inverse relationship for an object is so that it can update it automatically. The lines you posted are equivalent.
