Delegate funcations are not getting called or executed in turn-by-turn navigation when navigating with multiple waypoints.

[iamkhan001]

hi there,

I have implemented Mapbox navigation in my project. I need to navigate a path with multiple waypoints, and I want to detect when the user arrives at the waypoint and Navigation is ended. However, it's not calling delegate functions when the user arrives and navigation is ended.
But I have noticed that

Below is code to start turn by turn navigation

   guard let navigationRoutes else {
      self.parentView().showAutoDismissAlert(title: "Error!", message: "Navigation route not available!")
      return
    }
    
    let navigationOptions = NavigationOptions(
      mapboxNavigation: mapboxNavigation,
      voiceController: mapboxNavigationProvider.routeVoiceController,
      eventsManager: mapboxNavigationProvider.eventsManager(),
      predictiveCacheManager: mapboxNavigationProvider.predictiveCacheManager
    )
    navigationViewController = NavigationViewController(
      navigationRoutes: navigationRoutes,
      navigationOptions: navigationOptions
    )
    
    guard let navigationViewController else {
      self.parentView().showAutoDismissAlert(title: "Error!", message: "Navigation route not available!")
      return
    }
    navigationViewController.showsEndOfRouteFeedback = false
    navigationViewController.delegate = self
    navigationViewController.modalPresentationStyle = .fullScreen
    
    isNavigationStarted = true
    
    present(navigationViewController, animated: true)

Delegate functions

extension TripNavigationViewController: NavigationViewControllerDelegate, UINavigationControllerDelegate{
  
 func navigationViewController(_ navigationViewController: NavigationViewController, didArriveAt waypoint: Waypoint, after legIndex: Int) -> Bool {
    print("Arrived at waypoint: \(waypoint.name ?? "Unknown") (Leg Index: \(legIndex))")
    DispatchQueue.main.async {
      self.findNearbyStops()
    }
    return false
  }
  
  func navigationViewControllerDidDismiss(
    _ navigationViewController: NavigationViewController,
    byCanceling canceled: Bool
  ) {
    
    DispatchQueue.main.async {
      self.isNavigationStarted = !canceled
      
      if canceled {
        print("❌ Navigation was canceled by the user")
      } else {
        print("✅ Navigation has finished")
      }
      self.dismiss(animated: true, completion: nil)
    }

  }
  
}

I've been stuck on this for long and tried many solutions but nothing worked

Hi @iamkhan001

Thank you for the report. It looks like this delegate method currently only gets called for the final destination. This might change in future releases.

Currently, you can use the events publishers, e.g.

navigationProvider.mapboxNavigation.navigation().waypointsArrival
            .sink { [weak self] status in
                switch status.event {
                case let event as  WaypointArrivalStatus.Events.ToFinalDestination:
                        print("end of the route \(event.destination)")
                case let event as WaypointArrivalStatus.Events.ToWaypoint:
                    print("end of the leg \(event.legIndex)")
                default:
                    break
                }
            }
            .store(in: &lifetimeSubscriptions)
