How does one know when the CloudKit data in a CoreData+CloudKit (NSPersistentCloudKitContainer) has been fully synchronized. UseCase would be a user starts the App on a second device, user deletes then reinstalls the App, another User accepts a share and the share needs to sync.
Is the containerEventChanged Notification for 'import success' the definitive event?
CoreData: CloudKit: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _finishedRequest:withResult:](3403): Finished request: <NSCloudKitMirroringImportRequest: 0x600002345d10> 729A742A-7F3B-42F1-B04C-72705D41FFEF with result: <NSCloudKitMirroringResult: 0x600000c4edc0> storeIdentifier: 79FA5848-A135-41B1-A36A-09F2F914D23D success: 1 madeChanges: 0 error: (null)
As the sync could be time-consuming, is there a way to identify a single CloudKit record?

When you get a successful .import event your device is "current" with whats in iCloud. You can then use a fetch request to identify / check for interesting data.
Note that "current" here is caught-up-to the iCloud server, it doesn't imply anything about the state of other devices.
