I am beginner at Swift and a student.
I want to pop up detailed view when the GMSMarker is tapped. However when I tap GMSMarker, infoView will be called and then, infoView tapped, detailed view shows up on this code. How do I modify this? Isn't it possible to go straight to detailed view from GMSMarker without infoView?

Whenever a GMSMarker is tapped, you get the callback in GMSMapViewDelegate's method:
func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool
By default, when a GMSMarker is tapped, infoWindow for that marker pops up. In case you want something else to happen on marker tap, add it to the delegate method and return true.
func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool
{
//Your custom logic to move to another VC
return true
}
