Answer 1

If you just want to get the exact coordinates wherever you tapped whether on Overlay or not, then there is another delegate of GMSMapViewDelegate which is called whenever we tap on GoogleMaps. In this delegate you can get the exact coordinates where you tapped on map irrespective of tapping on an overlay.

Swift 3.0

 func mapView(_ mapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D) {
        print(coordinate.latitude)
        print(coordinate.longitude)
    }

If you want to get the coordinate only on tapping marker, then use this delegate method

func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
        print(marker.position.latitude)
        print(marker.position.longitude)
        return true
    }

Make sure to make your overlay as non-tappable

overlay.isTappable = false
