How to Display User's Place on Snippet Google Maps Swift - swift

Question

I have google map and want to display user's place (like city) in snippet.
How to do that?
here's my current code:
class ViewController: UIViewController, GMSMapViewDelegate, CLLocationManagerDelegate{
#IBOutlet weak var mapView: GMSMapView!
var latitude = -7.034323799999999
var longitude = 110.42400399999997
var locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
mapView.delegate = self
let camera = GMSCameraPosition.camera(withLatitude: Double(latitude), longitude: Double(longitude), zoom: 17)
mapView.animate(to: camera)
let markerImage = UIImage(named: "ic_home_detail_marker_location")
let markerView = UIImageView(image: markerImage)
let marker = GMSMarker()
marker.position = CLLocationCoordinate2DMake(Double(latitude), Double(longitude))
marker.isDraggable = true
marker.snippet = "\(marker.position)"
mapView.selectedMarker = marker
marker.iconView = markerView
mapView.selectedMarker = marker
marker.map = mapView
}
}

If you want to get the user's city or state name you have to use CLGeocoder.
var currentLatitude:Double!
var currentLongitude:Double!
var cityName:String!
var stateName:String!
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("locationManager function called")
// Fetch current location coordinates
let locValue:CLLocationCoordinate2D = (locationManager.location?.coordinate)!
currentLatitude = locValue.latitude
currentLongitude = locValue.longitude
print("Current Location = \(currentLatitude!), \(currentLongitude!)")
// Zoom to current location
let camera: GMSCameraPosition = GMSCameraPosition.camera(withLatitude: currentLatitude!, longitude: currentLongitude!, zoom: 17.0)
viewMap.camera = camera
// check for current city
CLGeocoder().reverseGeocodeLocation(locationManager.location!, completionHandler: {(placemarks, error) -> Void in
if error != nil {
print("Reverse geocoder failed with error" + (error?.localizedDescription)!)
return
}
if (placemarks?.count)! > 0 {
let pm = placemarks?[0]
self.cityName = (pm?.locality)!
self.stateName = (pm?.administrativeArea)
print("Current City: \(self.cityName!)")
print("Curret State: \(self.stateName!)")
}
else {
print("Problem with the data received from geocoder")
}
})
locationManager.stopUpdatingLocation()
}
Now you have the current city stored in a variable.
The next step is that when the user touches a marker, it should display the cityname. For this to achieve implement this:
This delegate must be added:
GMSMapViewDelegate
and this is the marker function, when user taps on it.
func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
mapView.delegate = self
marker.snippet = ("Current city: \(cityName!)")
// return false so as to show the marker details or
// return true to hide marker details.
return false
}
