I have a full SwiftUI project/app (In the AppStore) that I would like to add some CarPlay functionality. I have the entitlement correctly setup and am able to see the icon on the CarPlay simulator.

I have tried various info.plist configurations with various class configurations and only achieve crashes at the moment when starting the app in the simulator.

I'm a bit confused about the way to go about displaying views. I would like to start with a simple "Hello world" but even that is challenging :)

This question seems to be the kind of thing that I require but doesn't go in to enough details on the AppDelegate configuration.

iOS 15.4 - SwiftUI + CarPlay - State not updating

This looks promising but again not enough detail for me:

This too , but I suspect it's an older way of displaying the views.

If I could get help with a simple "Hello World" I would be most grateful!

From info.plist

 <key>UIApplicationSceneManifest</key>
        <dict>
            <key>UIApplicationSupportsMultipleScenes</key>
            <true/>
            <key>UISceneConfigurations</key>
            <dict>
                <key>CPTemplateApplicationSceneSessionRoleApplication</key>
                <array>
                    <dict>
                        <key>UISceneDelegateClassName</key>
                        <string>$(PRODUCT_MODULE_NAME).CarPlaySceneDelegate</string>
                    </dict>
                </array>
            </dict>
        </dict>

CarPlaySceneDelegate.swift

import Foundation
import CarPlay

class CarPlaySceneDelegate: UIResponder, CPTemplateApplicationSceneDelegate {
    
  func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene,
                                  didConnect interfaceController: CPInterfaceController) {
    
    let screen = CPInformationTemplate(title: "Root", layout: .leading, items: [CPInformationItem(title: "Hello", detail: "CarPlay")], actions: [])
    
    interfaceController.setRootTemplate(screen, animated: true, completion: { _,_ in
        // Do nothing
    })
  }
}

Thanks
