Polyline Tap in Google Maps

I wonder if there is a tap listener for polylines drawn in Google Map. The marker's tap is this:

func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {

return false

Is there any equivalent function for polylines? I believe in Google Maps version 3 for web, you have the ability to add event listener for polylines like this:

google.maps.event.addListener(elines[i], 'click', function()


Is this also possible in ios/swift?

You can use isTappable property of GMSPolyline.


If this overlay should cause tap notifications.

polyline.isTappable = true

Whenever the polyline is tapped, the GMSMapViewDelegate method didTapOverlay is called

func mapView(_ mapView: GMSMapView, didTap overlay: GMSOverlay) {
        //Write your code here
