hierarchicalRootRecordID
The record ID of the shared hierarchy’s root record.
Declaration
@NSCopying var hierarchicalRootRecordID: CKRecord.ID? { get }Discussion
CloudKit populates this property only for metadata that belongs to a shared record hierarchy. If the metadata is part of a shared record zone, the property is nil. This is because, unlike a shared record hierarchy, a shared record zone doesn’t have a nominated root record.
