If I have located (or created) a CNContact record on one device (e.g., iPhone), and I want to retrieve that same record programmatically from another device (e.g., iPad or Mac), is there any unique id that identifies that record? The identifier property on CNContact seems to be assigned for the local replica of the contact record, but I don't believe it can be used to retrieve the record on another device (e.g., using unifiedContact(withIdentifier...). I can unifiedContact(matching...) but not guaranteed to get same record if there are multiples with same predicate property values.
I'm pretty new to Swift and CNContactStore, so sorry if I'm missing something obvious.
