Expansion of Networking Concept in Swift iOS track

I'm familiar with Android, but I'm migrating into iOS. I'm trying to figure out how to best send request data via POST using the NSURLSession and related classes. I found the weather app videos helpful for URL requests with no appended request parameters, but I'd like to send information as well as receive.

This is what I've come up with by using Google and the API Docs. This currently works with my servlet, but I'm looking for best practices feedback here. This is not how my final implementation will be, this is what I've been using in my playground so don't fret over how I handle the response.

Please provide suggestions on how to better handle this, if any. 

var request = NSMutableURLRequest(URL: NSURL(string: "enter url here"))

request.HTTPMethod = "POST"

var dataString = "NAME=myname&PASSWORD=mypassword"
var requestBodyData: NSData = (dataString as NSString).dataUsingEncoding(NSUTF8StringEncoding)!

request.HTTPBody = requestBodyData


let sharedPOSTSession = NSURLSession.sharedSession()
let task:NSURLSessionDownloadTask = sharedPOSTSession.downloadTaskWithRequest(request, completionHandler: { (location: NSURL!, response: NSURLResponse!, error: NSError!) -> Void in

    if(error == nil){
        let dataPOSTObject = NSData(contentsOfURL: location)
        let loginPOSTDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(dataPOSTObject, options: nil, error: nil) as NSDictionary

        println(loginPOSTDictionary["permissions"]!)             

    }else{
        println(error)
    }

})

task.resume()
