[Solved] How do I get the Lat Long of where the user tapped? in Swift v3 and google maps sdk

by


I found the solution at: https://developers.google.com/maps/documentation/ios-sdk/events
by googling for didTapAtCoordinate, which I somehow knew was part of the SDK.

The most important line for me was: mapView.delegate = self. It’s possible that some other solutions I tried would have worked had I used mapView.delegate = self, but nothing else had mentioned it. Also, the func mapView is of course important so I can use the coordinates of where the user tapped. 

import UIKit
import GoogleMaps

override func loadView() {
  let camera = GMSCameraPosition.camera(withLatitude: 1.285,
                                        longitude: 103.848,
                                        zoom: 12)

  let mapView = GMSMapView.map(withFrame: .zero, camera: camera)
  mapView.delegate = self
  self.view = mapView
}

// MARK: GMSMapViewDelegate
class DemoViewController: UIViewController, GMSMapViewDelegate {
}

func mapView(_ mapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D) {
        print("You tapped at \(coordinate.latitude), \(coordinate.longitude)")
}//end func
