The persistent identifier of the session’s associated scene.

## Declaration

```swift
final var sceneSessionIdentifier: String? { get }
```

## Discussion

Discussion Use this property to determine which of your app’s scenes belongs with this session. You can configure a GroupActivity object with a SceneAssociationBehavior type that tells the system how to associate the activity with one of your app’s scenes. After matching the activity to a specific scene, the system places the scene identifier in this property.
