Answer 1

You can set the color and width of a polyline in MKMapViewDelegate function only. Check example below.

  public func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
      let polyLine = overlay as? MKPolyline
      let renderer = MKPolylineRenderer(overlay: overlay)
      renderer.lineWidth = 2.5
      renderer.strokeColor = UIColor(red: 47/255, green: 62/255, blue: 158/255, alpha: 1.0)
      return renderer
  }

Answer 2

You have to make mapView.delegate = self

Then implement this method:

func mapView(_ mapView: MGLMapView, strokeColorForShapeAnnotation annotation: MGLShape) -> UIColor {

  return .blue
}
