supportsGrouping
A Boolean value that indicates whether to group the device with others in the AirPlay UI.
Declaration
var supportsGrouping: Bool { get set }Discussion
This property provides a convenient way to send the same media stream to multiple devices and list them as a group in the AirPlay UI (AVRoutePickerView). For example, a set of speakers arranged around the room can implement stereo playback by each playing different audio channels from an audio stream.
When someone selects a media receiver in the AirPlay menu, the system checks if it supports grouping. If so, the AirPlay UI displays a checkbox next to any other media receivers that also support grouping and implement the same protocol (DDDevice.Protocol).
If a person selects multiple devices in the menu, the selected devices reorder next to each other in the list.
