NSManagedObject's hasChanges is true while changedValues is empty

Question

I am trying to observe individual NSManagedObject changes on NSManagedObjectContextWillSaveNotification:

- (void)managedObjectContextWi         


        

Answer 1

I encountered the same issue. Instead of getting the flags, I just checked if changedValues() is empty.

For Swift:

if !managedObject.changedValues().isEmpty {
    // Has some changed values
}
