## Declaration

```swift
nonisolated init(_ title: LocalizedStringKey, @ContentBuilder _ actions: () -> Actions, @ContentBuilder background: () -> some View, @ContentBuilder backgroundAccessoryView: @escaping (DocumentLaunchGeometryProxy) -> some View)
```

## Parameters

- `actions`: A content builder for returning the view’s actions.
- `background`: The background of the scene.
- `backgroundAccessoryView`: A content builder for returning the view’s background accessory view.

## Discussion

Discussion Use a DocumentGroupLaunchScene alongside any DocumentGroup scenes. If you don’t implement a DocumentGroup in the app declaration, you can get the same design by implementing a DocumentLaunchView.
