title: Adding geojson layer to google map in iOS
body: <p>I am writing my first iOS native app. I am trying to load a GeoJSON layer onto a google map in the app (map comes from the google maps sdk) but I can't find any way to do it. I'm proficient in the google maps javascript API but I'm sensing things in Swift are very different.</p>
  
  <p>How can I load a GeoJSON layer onto a map in a native iOS app?</p>
