First all of you have to enter a key in Info.plist file NSLocationWhenInUseUsageDescription

After adding this key just make a CLLocationManager variable and do the following

@IBOutlet weak var mapView: GMSMapView!
var locationManager = CLLocationManager()

class YourControllerClass: UIViewController,CLLocationManagerDelegate {

    //Your map initiation code 
    let mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
    self.view = mapView
    self.mapView?.myLocationEnabled = true

    //Location Manager code to fetch current location
    self.locationManager.delegate = self
    self.locationManager.startUpdatingLocation()
}


//Location Manager delegates
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    let location = locations.last

    let camera = GMSCameraPosition.cameraWithLatitude((location?.coordinate.latitude)!, longitude: (location?.coordinate.longitude)!, zoom: 17.0)

    self.mapView?.animateToCameraPosition(camera)

    //Finally stop updating location otherwise it will come again and again in this delegate
    self.locationManager.stopUpdatingLocation()

}

When you run the code you will get a pop up of Allow and Don't Allow for location. Just click on Allow and you will see your current location.

Make sure to do this on a device rather than simulator. If you are using simulator, you have to choose some custom location and then only you will be able to see the blue dot.
