title: Swift / How to get the current adress of Map pin
body: <p>I want to make <code>google map</code> integration, I already have a <code>GMSMapView</code> and it's working fine.</p>
  
  <p>But what I want to do exactly is that when I slide the Map and move to another part of the world get the address of the earth pin where is located fixed pin</p>
  
  <p>Unfortunately I can not find a solution anywhere. I can not place afixed pin in the center of screen.</p>
  
  <p>So I want to place the fixed pin and when the user try to move the map get  changed value of address depend on that pin where is located in the map </p>
