When my app starts it loads data (of vehicle models, manufacturers, ...) from JSON files into CoreData. This content is static.
Some CoreData entities have fields that can be set by the user, for example an isFavorite boolean field.
How do I tell CloudKit that my CoreData objects are 'static' and must not be duplicated on other devices (that will also load it from JSON files).
In other words, how can I make sure that the CloudKit knows that the record created from JSON for vehicle model XYZ on one device is the same record that was created from JSON on any other device?
I'm using NSPersistentCloudKitContainer.
