# configuration

The configuration options per experience.

## Declaration

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

## Discussion

Discussion You may modify the configuration at any time, but after the experienceController(_:prepareForTransitionUsing:) delegate callback returns, the system copies the configuration and uses it for the ensuing transition. Further modifications affect subsequent transitions.
