Can I access CloudKit's metadata fields with NSPersistentCloudKitContainer?

I've got a simple Core Data Entity that is synchronized with CloudKit via NSPersistentCloudKitContainer. I can read my local fields, but how can I read fields like "Created" & "Modified" from CloudKit?

Do I have to add them to my Core Data model and populate them myself?

P.S. In his fantastic WWDC talk "Using Core Data with CloudKit", at around 21:40, Nick Gillet talks about how Core Data entities in the CloudKit store are prefixed with "CD_" to separate the things that it manages from the ones CloudKit implements. Then he says: "You wouldn't believe how many people add modify date to their CKRecord". Like it's something redundant.
