Cannot use a predicate that compares dates in Magical Record

Question

I am making a method that will remove all of my NSManagedObjects that were not updated in the last sync.

- (void)removeStaleObjects {

        // Delete obje         


        

Answer 1

The problem is the name "updated" of your attribute. It conflicts with the isUpdated method of NSManagedObject. (See Core Data NSPredicate "deleted == NO" does not work as expected for a similar issue with a "deleted" attribute.)

If you rename your attribute, everything works as expected.
