I would like to hide a route map when I choose a new destination position. The problem now is that keep me the all oldest routes.
this a part of my code that draw a route every time the user tap on the map.

 override func viewDidLoad() 
 super.viewDidLoad()
 mapView.delegate = self
 let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.tapped(_:)))
 mapView.addGestureRecognizer(tapGestureRecognizer)
 

@objc func tapped (_ recognizer: UITapGestureRecognizer) 
 // Get point on screen
 let point = recognizer.location(in: mapView)

 // Convert point to NSValue
 let value = NSValue(cgPoint: point)

 // Get coordinates for point from screen
 let coordinates = mapView.geoCoordinates(fromScreenPoints: [value])
 // now handle the coordinates, as you wish
 endPointMP = SYGeoCoordinate(latitude: coordinates[0].latitude, longitude:coordinates[0].longitude)
 let markerEnd = SYMapMarker(coordinate: endPointMP!, image: UIImage(named: "Arrive")!)
 startPointMP = SYGeoCoordinate(latitude: SYPositioning.shared().lastKnownLocation?.coordinate?.latitude ?? 0, longitude: SYPositioning.shared().lastKnownLocation?.coordinate?.longitude ?? 0)
 let markerStart = SYMapMarker(coordinate: startPointMP!, image: UIImage(named: "Depart")!)
 mapView.add(markerEnd)
 mapView.add(markerStart)
 computeRoute(from: startPointMP!, to: endPointMP!)
 

func computeRoute(from fromCoordinate: SYGeoCoordinate, to toCoordinate:
 SYGeoCoordinate) 
 let startWaypoint = SYWaypoint(position: fromCoordinate, type: .start, name: "Begin")
 let endWaypoint = SYWaypoint(position: toCoordinate, type: .end, name: "End")
 let routingOptions = SYRoutingOptions()
 routingOptions.transportMode = .unknown// For other options see SYTransportMode
 routingOptions.routingType = .economic// For other options see SYRoutingType
 routing.computeRoute(startWaypoint, to: endWaypoint, via: nil, with: routingOptions)
 

best regards
