     let questions = myJSON["questions"] as! [[String:Any]] 
     //looping through all the array 
     for obj in questions{ 
      self.questionId = obj["id"] as! Int 
      let questionName = obj["ques"] as! String 
      let questionopta = obj["opta"] as! String 
      let questionoptb = obj["optb"] as! String 
      let questionoptc = obj["optc"] as! String 
      let questionoptd = obj["optd"] as! String

do { 
    if let json = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? [String : Any] { 

     for question in json["questions"] as? [[String : Any]] ?? [] { 

      guard 
       let questionId = question["quid"] as? Int, 
       let questionName = question["ques"] as? String, 
       let questionopta = question["opta"] as? String, 
       let questionoptb = question["optb"] as? String, 
       let questionoptc = question["optc"] as? String, 
       let questionoptd = question["optd"] as? String else { continue } 

      self.questionId = questionId 

      // ... 
     } 
    } 
} catch { 
    print(error) 
}
