Answer 1

if let tracks = readableJSON["tracks"] as? JSONStandard
{
  if let items = tracks["items"] as? NSArray
  {
     for i in 0..<items.count
     {
        let item = items[i] as? JSONStandard
        let name = item?["name"] as! String
        names.append(name)
        self.tableView.reloadData()
     }               
   }
}

I got my answer with line if let items = tracks["items"] as? NSArray instead of if let items = tracks["items"]

Here Simulator takes types itself and for device we have to specify data type as i have writtern as? NSArray for items
