var locationManager = CLLocationManager()
var locationMarker: GMSMarker!

all my problem is that I can't add optional marker when user touch in google maps.

Answer 1

In adding marker when user touch the map, use didTapAtCoordinate this was called after a tap gesture at a particular coordinate, but only if a marker was not tapped. Or, didLongPressAtCoordinate when long press gesture at a particular coordinate.

To add a marker, you need to create a GMSMarker object that includes a position and title and set its map.

The following example demonstrates how to add a marker to an existing GMSMapView object. The marker is created at coordinates 10,10, and displays the string "Hello world" in an info window when clicked.

let position = CLLocationCoordinate2DMake(10, 10)
let marker = GMSMarker(position: position)
marker.title = "Hello World"
marker.map = mapView
