title: Swift Google Maps smoothly rounded polylines
body: <p>I'm using GoogleMaps for iOS platform, Swift language.</p>
  
  <p>I draw the path according to the Google Maps documentation:</p>
  
  <pre><code> let path = GMSMutablePath()
   path.add(previousLocation)
   path.add(currentLocation)
  
   let line = GMSPolyline(path: path)
   line.strokeWidth = 5
   line.strokeColor = .blue
   line.map = mapView
  </code></pre>
  
  <p>My client complains that the route lines intersections must be smoothly rounded. How can I implement this? Some suggestions? </p>
  
  <p>Thanks!</p>
