I am developing an app that uses MusicKit to play music and then I need to have spoken words played to the user, while ducking the audio coming from MusicKit (application music player) the built in Siri voices are not off sufficient quality so I am using an external service to create an mp3 file and then play this back using AVAudioSession Sample code below the problem I am having is that .duckOthers is not ducking the Application Music Player output Is this a bug or am I doing this wrong? // Configure audio session for system-wide ducking try AVAudioSession.sharedInstance().setCategory(.playback, mode: .spokenAudio, options: [.duckOthers, .mixWithOthers]) try AVAudioSession.sharedInstance().setActive(true) // Set the ducking level to maximum try AVAudioSession.sharedInstance().setPreferredIOBufferDuration(0.005) // Create and configure audio player self.audioPlayer = try AVAudioPlayer(data: audioData) self.audioPlayer?.delegate = self self.audioPlayer?.volume = 1.0 // Ensure full volume for speech self.audioPlayer?.prepareToPlay() // Set the audio player's settings for maximum clarity self.audioPlayer?.enableRate = false self.audioPlayer?.pan = 0.0 // Center the audio self.audioPlayer?.play()

Hello, I've been banging my head against this for a couple of days now I can't get the CarPlay interface to work on my music app I see the error: Application does not implement CarPlay template application lifecycle methods in its scene delegate I've checked the sample code and developer guides and can't see my mistake My CarPlay delegate code is: class CarPlaySceneDelegate: UIResponder, CPTemplateApplicationSceneDelegate { var interfaceController: CPInterfaceController? var carPlayWindow: UIWindow? private let playerManager = MusicPlayerManager.shared private var playlists: MusicItemCollection<Playlist> = [] // MARK: - CPTemplateApplicationSceneDelegate Methods func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) { // Store reference to the interface controller to use throughout the app self.interfaceController = interfaceController // Request Apple Music authorization if needed requestMusicAuthorization() // Configure the interface with the now playing template and specified tabs setupCarPlayInterface(interfaceController) } func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didDisconnectInterfaceController interfaceController: CPInterfaceController) { // Clean up when CarPlay disconnects self.interfaceController = nil print("CarPlay disconnected") } func sceneDidBecomeActive(_ scene: UIScene) { // Called when the scene has moved from an inactive state to an active state print("CarPlay scene became active") } etc My info.plist contains: <key>UIApplicationSceneManifest</key> <dict> <key>UIApplicationSupportsMultipleScenes</key> <true/> <key>UISceneConfigurations</key> <dict> <key>CPTemplateApplicationSceneSessionRoleApplication</key> <array> <dict> <key>UISceneClassName</key> <string>CPTemplateApplicationScene</string> <key>UISceneConfigurationName</key> <string>TemplateSceneConfiguration</string> <key>UISceneDelegateClassName</key> <string>$(PRODUCT_MODULE_NAME).CarPlaySceneDelegate</string> </dict> </array> </dict> </dict> My one doubt is this entry in the plist: UISceneConfigurationName as I can't find any clarity in the docs how to use or implement this Can anyone suggest where I need to be looking? Thanks for your help!
