I am try to remove travelled polyline from google maps but can't find any proper solution on internet. I've drawn polyline by this,

let origin = "\(24.96487181552221),\(67.06045475052892)" //add worker lat long here
            let destination = "\(24.96485719),\(67.06699558)" //add job(customer) lat long here
            let url = "https://maps.googleapis.com/maps/api/directions/json?origin=\(origin)&destination=\(destination)&mode=driving&key=[Google-API-Key]"

            Alamofire.request(url).responseJSON { response in
                do{
                    let json = try JSON(data: response.data!)
                    let routes = json["routes"].arrayValue
                    for route in routes
                    {
                        let routeOverviewPolyline = route["overview_polyline"].dictionary
                        let points = routeOverviewPolyline?["points"]?.stringValue
                        self.path = GMSPath.init(fromEncodedPath: points!)

                        self.polyline = GMSPolyline(path: self.path)
                        self.polyline?.strokeColor = UIColor(hexString: "19C90E")
                        self.polyline?.strokeWidth = 3.0
                        self.polyline?.map = self.mapView

                    }
                }
                catch let error {
                    print(error)
                }
            }

here polyline is a GMSPolyline which i want to remove as user travel through it's path.

As per the GMSPolyline documentation, you can remove the polyline from the map by setting the GMSPolyline map property to nil. For example:

self.polyline?.map = nil

Alternatively, you can also remove all polylines or shapes by calling the GMSMapView clear method. For example:

mapView.clear()

I hope this helps!
