# playbackControl

The playback control interface for the remote session.

```
@property (readonly, nullable) NSObject<AVPlaybackUserInterfaceControllable> * playbackControl;
```

## Discussion

This property is always non-nil when obtained from a successful call to [`start()`](/documentation/AVSystemRouting/AVSystemRouteSession-gp78/start()).

> Important: Always update media playback state information regularly in the playbackControl object to ensure
> the system displays accurate information about the current media play state across a person’s
> devices and in system UI.
