The best way to assist exterior show in a SwiftUI iOS app?

What’s the present best-practice for supporting an exterior show in a SwiftUI iOS app in 2024? Not easy mirroring, however really displaying completely different content material than the machine.

The one docs I discovered require abandoning the SwiftUI App construction and “switching again to a full UIKit App Delegate”.

Is that this nonetheless the one choice?

Are there any full examples on learn how to accomplish this?

Even the examples I discovered I can’t get working b/c the registered delegate by no means will get known as.

Data.plist is configured as:

    UIApplicationSceneManifest
    
        UIApplicationSupportsMultipleScenes
        
        UISceneConfigurations
        
            UIWindowSceneSessionRoleExternalDisplayNonInteractive
            
                
                    UISceneConfigurationName
                    Exterior Show
                    UISceneDelegateClassName
                    $(PRODUCT_MODULE_NAME).ExternalDisplaySceneDelegate
                
            
        
    

And right here is the delegate class:

remaining class ExternalDisplaySceneDelegate: UIResponder, UIWindowSceneDelegate {
    var window: UIWindow?

    func scene(_ scene: UIScene,
               willConnectTo session: UISceneSession,
               choices connectionOptions: UIScene.ConnectionOptions) {

        print("exterior scene") // ⬅︎----- I can by no means get this to print

        guard let scene = scene as? UIWindowScene else {
            return
        }

        let content material = ExternalDisplayView()
        window = UIWindow(windowScene: scene)
        window?.rootViewController = UIHostingController(rootView: content material)
        window?.isHidden = false
    }
}

Am I doing one thing flawed?
Is there a greater means?

(Observe: I am solely fascinated with iOS 17 and/or iOS 18)

Thanks upfront.
