For Swift 2.0 Google Maps, to make your map view fit the polyline of the route you are drawing:

let path: GMSPath = GMSPath(fromEncodedPath: route)!
    routePolyline = GMSPolyline(path: path)
    routePolyline.map = mapView


    var bounds = GMSCoordinateBounds()

    for index in 1...path.count() {
        bounds = bounds.includingCoordinate(path.coordinateAtIndex(index))
    }

    mapView.animateWithCameraUpdate(GMSCameraUpdate.fitBounds(bounds))
