I actually think I figured it out. It seems I need to capture the category before I change it: // Save previous category self.previousCategory = audioSession.category And then set it back before I stop the audio session being active: do { if let category = self.previousCategory { try audioSession.setCategory(category) } try audioSession.setActive(false, options: .notifyOthersOnDeactivation) } catch { print(error) } I no longer get the error that an audio session/object is running.

Yes, just what I was looking for. Thank you. Question about this, I have a CPMapButton and added an accessiblityLabel but it does not seem to tap the button when I say "tap current location": lazy var currentLocationButton: CPMapButton = { let recenterButton = CPMapButton { [weak self] button in guard let self = self else { return } if let mapView = self.mapViewController?.mapView { mapView.setUserTrackingMode(.followWithCourse, animated: true, completionHandler: nil) } } recenterButton.accessibilityLabel = NSLocalizedString("Current Location", comment: "CarPlay: Current Location Button accessiblity") recenterButton.accessibilityHint = NSLocalizedString("Show the users current location on the map", comment: "CarPlay: Show current user location on the map") let bundle = Bundle.main recenterButton.image = UIImage(named: "carplay_locate", in: bundle, compatibleWith: traitCollection) return recenterButton }()

So you suggest using one of the API to recognize speech such as in this example? https://developer.apple.com/tutorials/app-dev-training/transcribing-speech-to-text

For those looking for a solution to this, I figured it out by accident. **I was using a AppDelegate.mm file that needed to change that to AppDelegate.m instead. **

Yes, you can use the Information template for a driving task app. This is shown in the CarPlay Programming Guide.

This was a bug in iOS 13 and was fixed, bug sadly has returned in iOS 15. See the following threads about this issue: https://developers.apple.com/forums/thread/127421 https://developer.apple.com/forums/thread/125631

This happens again in iOS 15.

Setting userTrackingMode will allow iOS to control the zoom. If you want full control you need to roll your own tracking of the user location.
