Z_PK Column in Core Data Database

Question

Is it possible to fetch the number from the Z_PK column created by Core Data? If so, would you fetch this column the same way you would fetch attributes you created manuall

Answer 1

You could use sqlite to directly access the columns created by CoreData.

However, you shouldn't depend on Z_PK or any of the columns to stay consistent. The schema could change (and has) between releases. Apple has stated this in WWDC videos.
