# playbackCoordinator(_:didIssue:completionHandler:)

Tells the delegate to expect playback soon and to start buffering media data in preparation.

## Declaration

```swift
func playbackCoordinator(_ coordinator: AVDelegatingPlaybackCoordinator, didIssue bufferingCommand: AVDelegatingPlaybackCoordinatorBufferingCommand, completionHandler: @escaping @Sendable () -> Void)
```

```swift
func playbackCoordinator(_ coordinator: AVDelegatingPlaybackCoordinator, didIssue bufferingCommand: AVDelegatingPlaybackCoordinatorBufferingCommand) async
```

## Parameters

- `coordinator`: The playback coordinator that issues the command.
- `bufferingCommand`: The command to execute. Before performing it, verify that its doc://com.apple.avfoundation/documentation/AVFoundation/AVDelegatingPlaybackCoordinatorPlaybackControlCommand/expectedCurrentItemIdentifier property value matches the item that you’re currently playing. If the command isn’t valid for the current item, ignore it and call the completion handler.
- `completionHandler`: A completion handler that your app must call when it finishes handling the command, either successfully or after beginning a suspension if it can’t handle the command currently. If the value of the command’s doc://com.apple.avfoundation/documentation/AVFoundation/AVDelegatingPlaybackCoordinatorPauseCommand/shouldBufferInAnticipationOfPlayback property is doc://com.apple.documentation/documentation/Swift/true, call the completion handler only after the player is ready for playback.

## Discussion

Discussion The coordinator issues this command when playback is currently in a paused state and the coordinator is expecting playback to start soon. It provides an appropriate opportunity to update your player UI to indicate that playback is in a waiting state.
