Unfortunately, Core Data-Specific sort descriptor docs are fairly lacking. As I mentioned it may be that NSSortDescriptor doesn't translate key paths like NSPredicate might. It may expect them to be appropriate to a SQL query. Considering that the attribute b or entity B is unambiguous (i.e. entity A does not have an attribute with the same name), have you tried passing just "b" as the key? Another option is passing "B.b" as the key. HTH, Keary Suska Esoteritech, Inc.
