Convert GPS coordinates to a city name / address in Swift

I have a latitude/longitude location that I want to convert to the location name String in Swift. What is the best way to do this? i believe it's best to use the reverseGeocodeLocation function but not exactly sure how to. This is what I have so far:

func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
    if (locationFixAchieved == false) {
        locationFixAchieved = true
        var locationArray = locations as NSArray
        var locationObj = locationArray.lastObject as CLLocation
        var coord = locationObj.coordinate
        var latitude = coord.latitude
        var longitude = coord.longitude

        getCurrentWeatherData("\(longitude)", latitude: "\(latitude)")
        reverseGeocodeLocation(location:coord, completionHandler: { (<#[AnyObject]!#>, <#NSError!#>) -> Void in
            <#code#>
        })

    }
}

func reverseGeocodeLocation(location: CLLocation!, completionHandler: CLGeocodeCompletionHandler!){

}

You need to write the code like this:

geocoder.reverseGeocodeLocation(currentLocation, completionHandler: {
            placemarks, error in

                if error == nil && placemarks.count > 0 {
                    self.placeMark = placemarks.last as? CLPlacemark
                    self.adressLabel.text = "\(self.placeMark!.thoroughfare)\n\(self.placeMark!.postalCode) \(self.placeMark!.locality)\n\(self.placeMark!.country)"
                    self.manager.stopUpdatingLocation()
                }
            })
