Core Data Set Relationship from Inverse

Question

I have a bunch of code that sets Core Data relationships via the inverse instead of the "addWhateverObject" methods. This usually works well in all of my applications, but I have one app where the relationships are being lost when the NSManagedObject context is being saved.

My question is setting a relationship in Core Data via the relationship's inverse valid or do you have to use the accessor methods to add objects to the relationship?

Thanks!

Yes, using the inverse is valid. Core data does all of the appropriate updating for you when you do that. See the comments on this question Core Data To-Many Relationship Creating Duplicates When Adding Object to Parent Entity
