ios - Trouble unwrapping JSON Array to a String Value -

i have been struggling json few days. trying create post request web server username, return information on said user. have managed json response 2 ways, cannot cast of elements of array string. using swiftyjson api too.

import uikit import foundation  class viewcontroller: uiviewcontroller {      var token = "barrymanilow"     var endpoint = "http://www.never.money/simple_app7.php"   @iboutlet weak var firstlabel: uilabel!  override func viewdidload() {     submitaction(self) }  func submitaction(sender: anyobject) {      let myurl = nsurl(string: "http://www.mindyour.money/simple_app7.php");     let request = nsmutableurlrequest(url:myurl!);     request.httpmethod = "post";      // compose query string     let poststring = "token=\(token)";      request.httpbody = poststring.datausingencoding(nsutf8stringencoding);      let task = nsurlsession.sharedsession().datataskwithrequest(request){         data, response, error in          if error != nil{             println("error=\(error)")             return         }          // print out response body         let responsestring = nsstring(data: data, encoding: nsutf8stringencoding)         println("responsestring = \(responsestring)")          //let's convert response sent server side script nsdictionary object:          var err: nserror?         var myjson = nsjsonserialization.jsonobjectwithdata(data, options: .mutableleaves, error:&err) as? nsarray  var json : json = json(data: data)          let results: anyobject? = myjson?.valueforkey("player_username")         println("\(results)") let result2 = json["player_username"].string       }      task.resume() } } 

however, doesn't seem working, can me?

i see when using nsjsonserialization you're casting json response nsarray, example first item's player_username swiftyjson do:

let result2 = json[0]["player_username"].string 

it should work without casting json[0] dictionary first because swiftyjson compiler knows json[0] dictionary.

if reason json[0] not automatically subscriptable, can do:

let playeronedic = json[0].dictionary let result2 = playeronedic["player_username"].string 

---

otherwise, without swiftyjson, have this:

if let playerone = myjson?[0] as? [string:anyobject] {     if let username = playerone["player_username"] as? string {         println(username)     } }
