How to use swiftyJson to get arrayvalue in TableView? - swift

Question

I use swiftyJson to parse data and, but do not know how to parse array.
Here is code.
import UIKit
import Alamofire
import SwiftyJSON
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
var json:JSON = JSON.null
var urlSession = URLSession(configuration: .default)
#IBOutlet weak var myTableView: UITableView!
var pokamon = [[String:AnyObject]]()
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return pokamon.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
var dict = pokamon[indexPath.row]
cell.nameLbl.text = dict["name"] as? String
cell.typesLbl.text = dict["types"]?[0] as? String
cell.hpLbl.text = dict["hp"] as? String
cell.subtypeLbl.text = dict["subtype"] as? String
if let image = URL(string: dict["imageUrl"] as! String){
let task = urlSession.downloadTask(with: image) { (url, repsponse, error) in
if error != nil{
print("sorry")
return
}
if let okURL = url{
do{
let downloadImage = UIImage(data: try Data(contentsOf: okURL))
DispatchQueue.main.async {
cell.myImage.image = downloadImage
}
}catch{
print("error")
}
}
}
task.resume()
}
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 224
}
override func viewDidLoad() {
super.viewDidLoad()
myTableView.delegate = self
myTableView.dataSource = self
Alamofire.request("https://api.pokemontcg.io/v1/cards").responseJSON(completionHandler: { response in
if response.result.isSuccess {
let json:JSON = try! JSON(data: response.data!)
let swiftyJsonVar = JSON(response.result.value!)
if let resData = swiftyJsonVar["cards"].arrayObject{
self.pokamon = resData as! [[String:AnyObject]]
}
if self.pokamon.count > 0{
self.myTableView.reloadData()
}
} else {
print("error: \(response.error)")
}
})
}
}
From cellForRowAt in tableView, it shows "Ambiguous use of 'subscript'" with below code, have no idea how to solve it. The rest like "name", "hp", and "subtype" are no problem!
cell.typesLbl.text = dict["types"]?[0] as? String
Could anyone help me with this error?
Thanks!

The compiler must know the type of any subscripted object. Tell the compiler that you expect an array of strings.
cell.typesLbl.text = (dict["types"] as? [String])?.first
In Swift 3+ all JSON values are Any not AnyObject so declare the array
var pokamon = [[String:Any]]()
