Access the current `UIWindowScene` and `UIWindow` from any SwiftUI view.

## Usage

### SwiftUI Lifecycle

Read the current `UIWindowScene` with `WindowSceneReader`

```swift
@main
struct MyApp: App {
var body: some Scene {
WindowGroup {
WindowSceneReader { windowScene in
ContentView()
}
}
}
}
```

alternatively, just add `windowScene()` if you only need the window scene on child views.

```swift
@main
struct MyApp: App {
var body: some Scene {
WindowGroup {
ContentView()
.windowScene()
}
}
}
```

On child views the `UIWindowScene` will be available in the `Environment`

### UIKit Lifecycle

```swift
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
if let windowScene = scene as? UIWindowScene {
let rootView = ContentView()
.windowScene(windowScene)

let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: rootView)
self.window = window
window.makeKeyAndVisible()
}
}
```

## Environment

```swift
@Environment(\.windowScene) var windowScene
```

The `@Environment(\.windowScene) var windowScene` defaults to the first connected `UIWindowScene` or `nil` if no `UIWindowScene` is connected.
