Get value from JSON file in Swift -

i have json file converted nsdictionary object. question how 1 single value out object? make httppost webside , json array values "success" , "userid" want check on success if true or false.

import uikit  class viewcontroller2: uiviewcontroller {  override func viewdidload() {     super.viewdidload()      // additional setup after loading view. }  override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }   @ibaction func httpbtn(sender: anyobject) {     posttoserver()     httppost() }  func posttoserver() {     println("button presed") }  func httppost() {     var poststring = "email=joakim@and.dk&password=123456"      //declare url     var url: nsurl! = nsurl(string: "http://95.85.53.176/nhi/api/app/login")     var request: nsmutableurlrequest = nsmutableurlrequest(url: url)      //declare httpmethod     request.httpmethod = "post"      //post data     request.httpbody = poststring.datausingencoding(nsutf8stringencoding)      let task = nsurlsession.sharedsession().datataskwithrequest(request){         data, response, error in          if error != nil         {             println("error=\(error)")             return         }          println("response =\(response)")          var responsestring = nsstring(data: data, encoding:    nsutf8stringencoding)          println("responsestring =\(responsestring)")           var error: nserror?          var myjson = nsjsonserialization.jsonobjectwithdata(data, options: .mutableleaves, error: &error) as? nsdictionary          println(myjson)     }        task.resume()   }  } 

output

responsestring =optional({"success":true,"userid":"62"}) optional({ success = 1; userid = 62; }) 

you can access using key value like

var success = myjson["success"]!.intvalue var userid = myjson["userid"]!.intvalue  if(success == 1) //if true {   //do    } 

same userid
