title: Marker clustering with google maps SDK for iOS?
body: <p>I am using Google Maps SDK in my iOS app, and I need to group markers which are very close to each other - basically need to use marker clustering like its shown in the attached url. I am able to get this functionality in the Android maps SDK, but I didn't find any library for the iOS Google Maps SDK.</p>
  
  <p>Can you please suggest any library for this? <strong>Or</strong> suggest a way to implement a custom library for this?</p>
