calendarIdentifier
A unique identifier for the calendar.
Declaration
var calendarIdentifier: String { get }Discussion
This property is set when the calendar is created and can be used as a local identifier. Use calendar(withIdentifier:) to get a calendar with the specified identifier.
A full sync with the calendar will lose this identifier. You should have a plan for dealing with a calendar whose identifier is no longer fetch-able by caching its other properties.
