We will now just briefly discuss the differences in project creation if CloudKit is enabled, and these differences are minor. An extra configuration option will appear in your .xcdatamodeld file, allowing you to specify which entities should be synced with CloudKit.

This is normally a checkbox in the entity’s attribute panel in the data model editor. Instead of NSPersistentContainer, NSPersistentCloudKitContainer will be added to the generated code, which is a subclass of NSPersistentContainer, designed to work with CloudKit.
