Coredata and NSOrderedSet - how is the order of the set defined?

Asked 2012-02-29T10:47:56.030

I had a look through the existing documentation and couldn't find anything that confirms the behaviour I am seeing.

Starting on iOS 5, CoreData relationships can be ordered and in this case the returned object is a NSOrderedSet.

Can anyone confirm that the order of the objects in the set matches the order in which they have been created?

Cheers, Rog

If you don't sort the order yourself using sortedArrayUsingComparator: then I believe the objects are sorted in the order in which they are added.

You can also manual set the order with with – insertObject:atIndex: .
