CoreData sort by creation order

Question

Wondering, if possible, how I would go about sorting entities from an NSSet by the order in which they were created.

I'm able to sort them by certain attributes, but can't work out how to sort by creation order.

Thanks

The only way to do this with Core Data is to provide a creationDate field in the Entity and fill this. You could fill this within the entity itself in -willSave for example, so that the controller that deal with your model does not have to mess with that.
