Hello,
I am working with sharing over Core Data. I would like to implement my own UI to share records and manage participants. In the CKShare's documentation we can read:
However, only the owner can delete a shared hierarchy’s root record. If a participant attempts to delete the share, CloudKit removes the participant. The share remains active for all other participants (https://developer.apple.com/documentation/cloudkit/ckshare).
However, when I delete a shared NSManagedObject (as a participant), using self.moc.delete(sharedProject), the object is deleted even for its owner.
On the other hand, accoring to the "Sharing Core Data objects between iCloud users" documentation (https://developer.apple.com/documentation/coredata/sharing_core_data_objects_between_icloud_users), to delete a share, we should use the purgeObjectsAndRecordsInZone(with:in:completion:) method. And that works, however, NSManagedObjectContext doesn't merge changes. Moreover, in the same documentation we can read:
Manages the participants of the share from the owner side using addParticipant(:) and removeParticipant(:), or stops the sharing by calling purgeObjectsAndRecordsInZone(with:in:completion:).
Unfortunately, calling that method from the owner side leads to deletion of the shared record.
Do you have any ideas how to receive a similar effect like in the UICloudSharingController?
