Say I am making Root <-> Child application (i.e. Manager <-> Employee).
Say Manager has predefined email and already granted userDiscoverability application permission (via CKContainer.requestApplicationPermission).
When Employee starts application, initialisation sequence automatically creates CKRecord (i.e. Employee record for time tracking), CKShare and silently invites Manager to CKShare.
For achieving this I am using CKContainer.discoverUserIdentity, then CKContainer.fetchShareParticipant, then CKModifyRecordsOperation which saves both CKRecord and CKShare.
After initialisation flow in private database of Employee I have record type of cloudkit.share which has 2 participants, Employee itself and Manager. Acceptance status of Manager is INVITED. Also I have URL link which I got after saving CKShare.
Now on Manager side I want silently accept CKShare invitation in order to access Employee record (i.e. for time tracking).
How to silently accept CKShare invitation without need of sending URL link via email, Messages.app, without using UICloudSharingController, etc.?
Is it possible to purely programmatically, silently, using CloudKit only share CKShare from one side and accept it on other side?
Thank you!
