I have a slight problem, I am unable to remove the previous polyline created from the previous search.
I have looked at google documentation but i am unable to find the right answers.
let routes = json["routes"].arrayValue
for route in routes
{
let routeOverviewPolyline = route["overview_polyline"].dictionary
print("routesOVER:",routeOverviewPolyline)
let points = routeOverviewPolyline?["points"]?.stringValue
let path = GMSPath.init(fromEncodedPath: points!)
let polyline = GMSPolyline(path: path)
if polyline != nil {
print(polyline)
polyline.strokeColor = .black
polyline.strokeWidth = 10.0
polyline.map = self.googleMaps
}
}
}
catch let error as NSError {
print(error)
}
in the google maps, 2 polylines are shown. 1 from the previous search and another from the current search
