I have an iOS 17+ app (SwiftUI lifecycle, @UIApplicationDelegateAdaptor) with the granted com.apple.developer.carplay-communication entitlement. It's a voice-message app for family (leave/listen to short audio messages). The app does not appear in Settings → General → CarPlay, nor on the CarPlay Home grid, on a real head unit — across multiple TestFlight builds and full phone reboots. The iPhone app itself launches fine. Verified: The App Store distribution provisioning profile carries com.apple.developer.carplay-communication. The build is signed with that entitlement. Info.plist declares a CPTemplateApplicationSceneSessionRoleApplication scene with UISceneClassName = CPTemplateApplicationScene, a UISceneConfigurationName, and UISceneDelegateClassName pointing to a CPTemplateApplicationSceneDelegate. The delegate synchronously sets a root CPListTemplate in templateApplicationScene(_:didConnect:). My questions: Does a CarPlay Communication app require SiriKit messaging support (INSendMessageIntent, INSearchForMessagesIntent, INSetMessageAttributeIntent, the Siri entitlement, NSSiriUsageDescription, INIntentsSupported) in order to be registered/shown on the CarPlay dashboard? My app currently uses custom CPListTemplate rows with a direct audio recorder and no SiriKit intents. How can I confirm whether the App Store / TestFlight–re-signed build actually carries the carplay-communication entitlement at runtime? For an audio-message app that must never transcribe audio, is INOutgoingMessageType.outgoingMessageAudio the correct approach, and should playback use the SiriKit read flow rather than CPNowPlayingTemplate (which appears to require the Audio entitlement)?

CarPlay Communication app not appearing on the CarPlay dashboard — is SiriKit messaging support required for registration?
