Use of unresolved identifier - json

Question

In my Swift code to handle push notification I have this image:
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
var tableView:UITableView?
var items = NSMutableArray()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func viewWillAppear(animated: Bool) {
let frame:CGRect;(x:0, y: 100, width: self.view.frame.width, height: self.view.frame.height-100)
self.tableView = UITableView(frame: frame)
self.tableView?.dataSource = self
self.tableView?.delegate = self
self.view.addSubview(self.tableView!)
let btn = UIButton(frame: CGRect(x: 0, y: 25, width: self.view.frame.width, height: 50))
btn.backgroundColor = UIColor.cyanColor()
btn.setTitle("EKLE", forState: UIControlState.Normal)
btn.addTarget(self, action: "addData", forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(btn)
}
func addData(){
RestApiManager.sharedInstance.getRandomUser { json -> Void in
let results = json["results"]
for (index: String, subJson: JSON) in results{
let user: AnyObject = subJson["user"].object
self.items.addObject(user)
dispatch_async(dispatch_get_main_queue(), {
tableView?.reloadData()
})
}
}
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return items.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell?
if cell == nil{
cell = UITableViewCell(style: UITableViewCellStyle.Value1, reuseIdentifier: "cell")
}
let user:JSON = JSON(self.items[indexPath.row])
let picURL = user["picture"]["medium"].string
let url = NSURL(string: picURL!)
let data = NSData(contentsOfURL: url!)
cell?.textLabel?.text = user["username"].string
cell?.imageView?.image = UIImage(data: data!)
return cell!
}
}
Here is the error:
Use of unresolved identifier 'subJson'
in line let user: AnyObject = subJson["user"].object
How would this be fixed?

Answer 1

If you are using Swift 2 (Xcode 7) the syntax for looping over a dictionary with typed parameters has changed.
Now you should do like this:
for (index, subJson):(String, JSON) in results {
let user: AnyObject = subJson["user"].object
self.items.addObject(user)
dispatch_async(dispatch_get_main_queue(), {
tableView?.reloadData()
})
}
Old way:
(index: String, subJson: JSON)
New way:
(index, subJson):(String, JSON)
