I am facing one issue where I have created a car play scene delegate file but it never gets executed.
Here is my code for the app
@main
struct FredScannerProApp: App {
@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
Here is app delegate file
class AppDelegate: UIResponder, UIApplicationDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
do
{
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback)
try AVAudioSession.sharedInstance().setActive(true)
}
catch
{
print(error)
}
// This will enable to show nowplaying controls on lock screen
application.beginReceivingRemoteControlEvents()
return true
}
// MARK: UISceneSession Lifecycle
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
if (connectingSceneSession.role == UISceneSession.Role.carTemplateApplication) {
let scene = UISceneConfiguration(name: "CarPlaySceneConfiguration", sessionRole: connectingSceneSession.role)
scene.delegateClass = CarPlaySceneDelegate.self
return scene
} else {
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
}
func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
return true
}
func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
}
Here is info plist file

Here is carplayscenedelegate file
class CarPlayDelegate: UIResponder {
var carPlaymanager = CarPlaySceneDelegate()
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
// Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
if scene is CPTemplateApplicationScene, session.configuration.name == "CarPlaySceneConfiguration" {
// MemoryLogger.shared.appendEvent("Template application scene will connect.")
print("Connected")
}
}
func sceneDidDisconnect(_ scene: UIScene) {
// Called as the scene is being released by the system.
// This occurs shortly after the scene enters the background, or when its session is discarded.
// Release any resources associated with this scene that can be re-created the next time the scene connects.
// The scene may re-connect later, as its session was not neccessarily discarded (see `application:didDiscardSceneSessions` instead).
}
func sceneDidBecomeActive(_ scene: UIScene) {
// Called when the scene has moved from an inactive state to an active state.
// Use this method to restart any tasks that were paused (or not yet started) when the scene was inactive.
}
func sceneWillResignActive(_ scene: UIScene) {
// Called when the scene will move from an active state to an inactive state.
// This may occur due to temporary interruptions (ex. an incoming phone call).
}
func sceneWillEnterForeground(_ scene: UIScene) {
// Called as the scene transitions from the background to the foreground.
// Use this method to undo the changes made on entering the background.
}
func sceneDidEnterBackground(_ scene: UIScene) {
// Called as the scene transitions from the foreground to the background.
// Use this method to save data, release shared resources, and store enough scene-specific state information
// to restore the scene back to its current state.
}
}
extension CarPlayDelegate : CPTemplateApplicationSceneDelegate{
/// Connects the root template to the CPInterfaceController.
func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) {
self.carPlaymanager.connect(interfaceController)
}
// CarPlay disconnected
private func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didDisconnect interfaceController: CPInterfaceController) {
self.carPlaymanager.disconnect()
}
}
but somehow it's not attaching carplay instance i don't know what's going on? If someone could help me in this. I really appreciate it.
Also, Let me know if you want demo project, I will provide same,
Thank you
