I'm having a little trouble getting a self-incrementing attribute to work in the awakeFromInsert override.


What do you want to do with this attribute?

When using Core Data, you don't need to define your own primary or foreign keys. Every object has an object ID that acts conceptually as its primary key and is maintained for you by Core Data. Relationship maintenance is similarly handled for you by Core Data.
