# timeJumpedOriginatingParticipantKey

A key to retrieve a unique identifier of the participant that caused the time jump.

```
class let timeJumpedOriginatingParticipantKey: String
```

## Discussion

Use this key to retrieve a UUID value for the participant in a coordinated playback session that caused the time jump. The returned UUID reresents a value in the playback coordinator’s [`otherParticipants`](/documentation/AVFoundation/AVPlaybackCoordinator/otherParticipants) array.
