The value in this property determines what action, if any, to take when the target of the reference object—that is, the object pointed to in the
record property—is deleted. When this property is set to
CKReference, deleting the target object deletes any records that contain that reference in one of their fields. When this property is set to
CKReference, deleting the target object does not delete any additional objects.
