I have the same problem. Have you find any answer for this?

I have the same problem, when i used NSPersistentHistoryTrackingKey enable for non-cloud container, it auto sync my coredata to CloudKit. I have also tried setting the container's cloudKitContainerOptions property to nil but CloudKit sync still occur. But when i not enable NSPersistentHistoryTrackingKey for non-cloud container , it give me error like, Error : File is in Read Only mode due to Persistent History being detected but NSPersistentHistoryTrackingKey was not included. Please explain me what is use of NSPersistentHistoryTrackingKey for cloud sync process.
