Core Data - dual inverse relationships | MacRumors Forums
One thing I always wondered about Core Data is why the compiler would warn you if you didn't specify the inverse relationship. After reading. If I create two separate relationships I then have to create two inverse- relationships in the "transaction" entity (transferFrom and transferTo). It seems that Apple really, really wants you to have those inverse relationships. In fact, they pretty much say so in the Core Data documentation.
