didUpdateLocations에서 방향 경로 다시 그리기

Question

방향 경로를 다시 그리고 현재 위치로 마커를 옮기고 싶습니다.
현재는 didUpdateLocations 내부에서이 작업을 수행하고 있지만 동시에 여러 마커와 경로를 그리기 때문에 이상하게 보입니다.

let location = locations.last 

let destination = CLLocation(latitude: order!.user_coord![0], longitude: order!.user_coord![1]) 

let origin = CLLocation(latitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!) 

self.drawPath(startLocation: origin, endLocation: destination) 

self.createMarker(titleMarker: order!.store_name!, iconMarker: UIImage(named: "icons8-user_filled")!, latitude: order!.user_coord![0], longitude: order!.user_coord![1]) 

self.createMarker(titleMarker: "User", iconMarker: UIImage(named: "icons8-mountain_biking")!, latitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!) 

let camera = GMSCameraPosition.camera(withLatitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!, zoom: 17.0) 
self.map.animate(to: camera) 
locationManager.stopUpdatingLocation()

이

drawFinished = false 

if(!drawFinished) 
{ 
    drawFinished = true 

    let location = locations.last 

    let destination = CLLocation(latitude: order!.user_coord![0], longitude: order!.user_coord![1]) 

    let origin = CLLocation(latitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!) 

    self.drawPath(startLocation: origin, endLocation: destination) 

    self.createMarker(titleMarker: order!.store_name!, iconMarker: UIImage(named: "icons8-user_filled")!, latitude: order!.user_coord![0], longitude: order!.user_coord![1]) 

    self.createMarker(titleMarker: "User", iconMarker: UIImage(named: "icons8-mountain_biking")!, latitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!) 

    let camera = GMSCameraPosition.camera(withLatitude: (location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!, zoom: 17.0) 

    self.map.animate(to: camera) 

    locationManager.stopUpdatingLocation() 

    } 

didUpdate

에있는 viewDidLoad에서 변수

var drawFinished:Bool!

내 코드입니다

이 마커와 난 그냥 그것을 시도 업데이트에서 방향 경로를 중지합니다이

func clearMapOverlays() 
    { 
    for dl in self.myMapView.overlays 
    { 

     if(dl is GMSPolyline) 
     { 

      self.myMapView.remove(dl) 

     } 


    } 

    self.myMapView.setNeedsDisplay() 

    for name in self.myMapView.annotations 
    {       

      self.myMapView.removeAnnotation(anno) 

    } 


}
