# configuration

The configuration options per experience.

```
@MainActor final var configuration: AVExperienceController.Configuration
```

## Discussion

You may modify the configuration at any time, but after the [`experienceController(_:prepareForTransitionUsing:)`](/documentation/AVKit/AVExperienceController/Delegate-swift.protocol/experienceController(_:prepareForTransitionUsing:)) delegate callback returns, the system copies the configuration and uses it for the ensuing transition. Further modifications affect subsequent transitions.
