Alamofire JSON请求失败

Question

So I have the following code

@IBOutlet var jokes_list: UITableView!
var CountCells = 0
var CellsData = [NSArray: NSArray]()

override func viewDidLoad() {

    super.viewDidLoad();

    Alamofire.request("http://localhost:8080/jokes.php").responseJSON{ response in
        debugPrint(response.result.value)   // result of response serialization

        if let JSON = response.result.value as? [NSArray: NSArray] {
            self.CellsData = JSON
            self.CountCells = JSON.count
            self.jokes_list.reloadData()
        }else{
            debugPrint("failed")
        }
    }



    // Do any additional setup after loading the view, typically from a nib.
}

I get the debugPrint(response.result.value) output, but I also get a failed from the else statement.

A bit of the output from the debugPrint(response.result.value)

Optional(<__NSArrayI 0x7fc9c6056a00>(
{
    added = "2017-01-10 19:07:14";
    description = "Ora de religie \U00een scoala. Profesoara: \U2013 Si copii, amintiti-va permanent: cei care vor \U00eenvata pentru note de 9 si 10 vor nimeri \U00een

It's a very long output, so I don't think I can paste everything here, however the question is why can't I set the json as an array to CellsData in the code, so I can use it to show the list.

Answer 1

as? [NSArray: NSArray] as? [NSArray: NSArray] definitively isn't correct, there-for the cast fails and the else branch is executed. It means that you are expecting a dictionary where keys and values are of type NSArray , but you have an array or dictionaries, so it should read as? [[String: Any]] as? [[String: Any]] or similar, depending on the response you didn't provide fully.

Also var CellsData = [NSArray: NSArray]() must pe changed respectively. (btw: please familiarize yourself with cocoa touch / swift naming conventions)
