TableView.reloadData() is not working ? (SWIFT)

Question

I am developing a Quiz App which fetches questions from a JSON. I have already used reloadData for TableView many times & worked as expected. But now I am fetching Questions

Answer 1

You need to reload your tableview inside Alamofire block

And so it will look like

  Alamofire.request(.GET, "http://www.wis.com/index.php/capp/chapter_questions_details/\(CourseID)/\(EID)/10")
            .responseJSON { (_, _, data, _) in
                println(data)
                let json = JSON(data!)
                let catCount = json.count
                for index in 0...catCount-1 {
                    let q = json[index]["QUESTION"].string
                    self.QArray.append(q!)
                    println(self.QArray)
                }
        self.progress.dismiss()
        self.Exam.reloadData()
  }

and yes ofcourse, as per given answers and comments,

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return self.QArray?.count ?? 0 // will return 0 rows if QArray is empty
}

This may help!
