# isReady

Indicates whether the media source is ready to begin playback.

```
@MainActor var isReady: Bool { get }
```

## Discussion

This property should transition from `false` to `true` once the source has loaded enough data to
start playback, and should not revert. Use [`isBuffering`](/documentation/AVKit/AVPlaybackUserInterfacePlaybackControllable-9he54/isBuffering) to track temporary stalls that may
occur after this point.
