iOS 16 introduces new extension type that allows third-party streaming devices to be available via standard audio and video routing menu.
This opens an opportunity to provide support for Chromecast or Mirocast streaming devices in system menu. Developers yet to implement this feature in their apps though.
Apple Developer: DeviceDiscoveryExtension
Developer:Check documentation, restrictions.
QA engineer:Business as usual.
PM/DM:Monitor availability of the feature. Consider adding proper wording to apps that might rely on third-party streaming solutions.
