I’m working on a project that includes selecting an AirPlay endpoint, and I wondered how the Spotify guys made the following choice in the application of available AirPlay endpoints (you can see the AirPlay icon / message at the bottom of the application, which, when listening, leads to you will see through the Control Center, similar to the Action Sheet):

From what I know, the only “publicly available" API that can be used for this kind of thing is MPVolumeView , which is not necessarily the same as the volume controller and the button for launching such an action sheet.
