Declaration
@MainActor class CPNowPlayingPlaybackRateButtonOverview
CPNowPlayingPlaybackRateButton is a concrete subclass of CPNowPlayingButton. Use the button’s handler to invoke your existing functionality for cycling through playback rates, using the same MPChangePlaybackRateCommand that you provide to MPRemoteCommandCenter.
CarPlay uses MPRemoteCommandCenter to observe changes to the playback rate and updates the button’s appearance accordingly.
