I am trying to run my navigation app on a physical device, and want to view it using CarPlay Simulator (through XCode additional tools, NOT Hardware->Display->CarPlay), however, when I try to use the app, device has a Red dot next to it, and the simulator shows nothing.
What I've tried:
Running on a real CP device(my car): App works as intended, but want to run simulator so I can have live debugging
Forgetting CP device and reconnecting
All Steps of "Troubleshooting CP Simulator" (Updating to latest iOS, restarting phone, turn off hotspot, not connected to any other CP devices, ensure Firewall allows incoming connections)
Tried both Xcode 13 CP sim and Xcode 14 beta CP sim
Tried both work and personal laptops/phones
Ideas:
I am running on a M1 laptop, which could be messing with something. I am also running my Xcode in Rosetta(app has packages that cannot compile without Rosetta), but I don't believe this should be a problem because I am running on a physical device not Xcode simulator.
Also can't run on Hardware->Display->CarPlay because of
Application does not implement CarPlay template application lifecycle methods in its scene delegate and I can't figure out how to fix ("EXCLUDED_ARCHS[sdk=iphonesimulator*]"= "arm64" does not work)

CarPlay Simulator not receiving microphone input (Siri)
Running carplay simulator Version 1.1 (480.26)
Running on: M1 Macbook Pro running macOS Ventura 13.3.1
Connected to: iPhone 13 pro max running iOS 16.4 (20E246)
When launching Siri by "Hey Siri", the, the siri indicator apppears and I am able to communicate and send a command, such as "send a text".
Then, the Siri will say "who do you want to message", but it is no longer able to hear my voice as input.
Assuming that I have an iOS app which is managing the payment method of the user (e.g. credit card), what is preventing me to build a CarPlay app (e.g. EV charging app) with a button that triggers the payment of the charging station?
I mean, what are the advantages that will be introduced with iOS 16 that will allow the payment of gas stations from CarPlay?

I am developing CarPlay addition on our app. Which is distributed with the Enterprise In distribution method, so we do not have a product in the App Store. I am wondering if CarPlay support can be provided in applications distributed with the Enterprise in distribution method?
If this is not possible, I will inform management that this is not possible.
I am waiting for your answers, thanks.

Hi
I identified an issue that I cannot resolve with CarPlay. I am now rewriting an existing app that I initially created with ObjectiveC/Swift/UIKit. The new app should be super elegant, and of course SwiftUI based.
The thing is, if I use the old App Lifecycle (using App Delegates or Scene Delegates) without SwiftUI, everything works fine and smooth. However, I don't really want that, but rather have a single code base and not mess with ****** workarounds.
The funny thing is, if I place the @main item to the SwiftUI part, it tells me the life cycle would not be implemented, but it is.
Anybody has an idea?
Or this is a bug in SwiftUI / CarPlay?
I was trying to find some original code reference from Apple related to SwiftUI base apps and having a CarPlay 'extension' but couldn't find any - the latest WWDC code example was still based on the old framework
Thanks
Marco

func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {

}
the Scene Delegate that I used, but is largely ignored is
import UIKit
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
print(scene.debugDescription)
print(session.debugDescription)
print(connectionOptions.debugDescription)
guard let _ = (scene as? UIWindowScene) else { return }
}
func sceneDidDisconnect(_ scene: UIScene) {
print(scene.debugDescription)
}
func sceneDidBecomeActive(_ scene: UIScene) {
print(scene.debugDescription)
}
//...
}
The CarPlay delegate is this
class CarPlaySceneDelegate: UIResponder {
var interfaceController: CPInterfaceController?
}
extension CarPlaySceneDelegate: CPTemplateApplicationSceneDelegate {
func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) {
self.interfaceController = interfaceController
self.interfaceController?.delegate = self
}
private func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didDisconnect interfaceController: CPInterfaceController) {
self.interfaceController = nil
}
}
extension CarPlaySceneDelegate: CPTabBarTemplateDelegate {
func tabBarTemplate(_ tabBarTemplate: CPTabBarTemplate, didSelect selectedTemplate: CPTemplate) {
}
}
extension CarPlaySceneDelegate: CPInterfaceControllerDelegate {
func templateWillAppear(_ aTemplate: CPTemplate, animated: Bool) {
print("templateWillAppear", aTemplate)
}
func templateDidAppear(_ aTemplate: CPTemplate, animated: Bool) {
print("templateDidAppear", aTemplate)
}
func templateWillDisappear(_ aTemplate: CPTemplate, animated: Bool) {
print("templateWillDisappear", aTemplate)
}
func templateDidDisappear(_ aTemplate: CPTemplate, animated: Bool) {
print("templateDidDisappear", aTemplate)
}
