How To increase index of Array when the value is Dynamic (Swift)

Question

I am Getting a Dynamic Array which Consist (Dictionary with Array ) and want to increase the Index of Array and will go on to Next Dictionary on action.

After Parsing The Value in swapLibs

var currentQuizIndex = 0
func Dataparsed() {
    ServiceManager.service(ServiceType.POST, path: urslStr, param: nil, completion: {  (sucess, response, error, code) -> Void in
        if (code == 200) {
            let QuizData  = (swapLibs?.valueForKey("quiz") as! NSArray)
            let  quizData = playInfo.PlayQuizInfo(QuizData[self.currentQuizIndex] as? NSDictionary)
            self.playQuizArray.addObject(quizData)
            self.playQuizTitle?.text = quizData.quizQuestion
            self.playQImage.sd_setImageWithURL(NSURL(string: quizData.quizQImage!))
            self.QNumber?.text = "\(self.Qno)/\(self.noofQuestion)"
        }
    })
}

And The Modal is

class playInfo: NSObject {

    var quizId :           String? = ""
    var quizQId :          String? = ""
    var quizQImage :       String? = ""
    var quizQuestion :     String? = ""
    var quizType :         String? = ""
    var quizIndex :        String? = ""


    class func  PlayQuizInfo(dict: NSDictionary?) -> playInfo {

        let Pinfo = playInfo()
        Pinfo.WrapPlayQuiz(dict)
        return Pinfo
    }

    func WrapPlayQuiz(dict: NSDictionary?)  {
        if dict == nil {
            return
        }
        self.quizId           = dict!.objectForKey("quizId")    as? String
        self.quizIndex        = dict!.objectForKey("index")     as? String
        self.quizQImage       = dict!.objectForKey("QuesImage")     as? String
        self.quizQuestion     = dict!.objectForKey("question")  as? String
        self.quizType         = dict!.objectForKey("Type")      as? String
        self.quizQId          = dict!.objectForKey("questionId")      as? String
    }

}

Here is Structure

{  
   "quiz":[  
      {  
         "quizId":"7295",
         "QuesImage":"http:\/\/proprofs.com\/api\/ckeditor_images\/man-approaches-woman1(1).jpg",
         "question":"How do you know him?",
         "questionId":"216210",
         "Type":"PQ",
         "index":4,
         "keys":[  
            {  
               "answerId":"8266",
               "option":"He's in one or more of my classes, and we're good friends.",
               "AnsImage":"Image Not Available"
            },
            {  },
            {  },
            {  },
            {  }
         ]
      },
      {  },
      {  },
      {  },
      {  },
      {  },
      {  },
      {  },
      {  },
      {  },
      {  },
      {  }
   ]
}

Each Dictionary is Containing same Key As above

Any Help Will Be Appreciated.Thanks.

So you are not using keys? And you want to fill playQuizArray with all the data from the quiz array in response? — Bista

As I don't have ServiceManager at my end so I have created this code hypothetically. It might solve you issue of saving all data in to one array. It also adds keys in to array as an object.

EDIT 1 : correct QuizKey object array formation. Let me know if any kind of error occurs, as I am unable to test it at my end.

Edit 2: I have made a general ViewController its working perfectly.Try running this View Controller file and you will see the results.

class TestVC: UIViewController {

    //An Array similar to the response you are getting from the server
    var response:[AnyObject] = [
        [
            "quizId" : "1111",
            "QuesImage" : "http://proprofs.com/api/ckeditor_images/man-approaches-woman1(1).jpg",
            "question" : "How do you know him?",
            "questionId" : "216210",
            "Type" : "PQ",
            "index" : 4,
            "keys":[
                [
                    "answerId":"8266",
                    "option":"He's in one or more of my classes, and we're good friends.",
                    "AnsImage":"Image Not Available"
                ],
                [
                    "answerId":"8266",
                    "option":"He's in one or more of my classes, and we're good friends.",
                    "AnsImage":"Image Not Available"
                ],
                [
                    "answerId":"8266",
                    "option":"He's in one or more of my classes, and we're good friends.",
