MBS( "Events.Item.CalendarItemIdentifier"; EKCalendarItem )


Parameter Description Example value
EKCalendarItem The reference to the calendar item: an event or reminder. $item


Returns ID or error.


Returns a unique identifier for a calendar item.
Item identifiers are not sync-proof in that a full sync will lose this identifier, so you should always have a back up plan for dealing with a reminder that is no longer fetchable by this property, e.g. by title, etc..
You only need this function to match a reference number from our plugin to the UUID used by calendar identifier.
