title: Get LAT and LONG from tapped overlay in Google Maps
body: <p>When a user taps an overlay, the following code is triggered:</p>
  
  <pre><code>func mapView(_ mapView: GMSMapView, didTap overlay: GMSOverlay) {
  
  
      }
  </code></pre>
  
  <p>I wonder if we can extract the exact LAT and LONG coordinates of the overlay that has been tapped?</p>
  
  <p>Thanks!</p>
