Declaration
var reservationNumber: String? { get }Discussion
Provide your system’s reference number for the reservation. Use a consistent, unique identifier for each reservation. If you also provide reservation information with Siri Event Suggestions Markup on your website or in emails, use the same value for the reservationId in the reservation markup.
For a multipart booking, such as round-trip travel, you may provide the same reservationNumber for each reservation.
