JSON Parsing Swift using JSONPlaceholder - ios

Question

I'm playing with Swift and JSONPlaceholder. I want to retrieve all the data contained in: https://jsonplaceholder.typicode.com/photos
I created a function that is acceding to the url, downloading the JSON but then I don't know how can I obtain the title and the thumbnailUrl to pass then for populate the tableView. In the past I used this code but now it's not working because on the JSONPlaceholder there are no array.
Any help for re-arrange the code for read and obtain the jsonplaceholder elements?
func loadList(){
let url = URL(string: urlReceived)
var myNews = NewInfo()
let task = URLSession.shared.dataTask(with: url!) {
(data, response, error) in
if error != nil{
print("ERROR")
}
else{
do {
if let content = data{
let myJson = try JSONSerialization.jsonObject(with: content, options: .mutableContainers)
//print(myJson)
if let jsonData = myJson as? [String : Any] {
if let myResults = jsonData["list"] as? [[String : Any]]{
//dump(myResults)
for value in myResults{
//Read time string from root
if let time = value ["dt_txt"] as? String{
myNews.time = time
}
//Read main container
if let main = value["main"]
as? [String : Any]{
if let temperature = main["temp"] as? Double {
myNews.temperature = String(temperature)
}
}
//Read from weather container
if let weather = value["weather"] as? [[String: Any]]{
for value in weather{
if let weatherContent = value["description"] as? String{
myNews.weatherDescription = weatherContent
}
}
}
self.myTableViewDataSource.append(myNews)
}
dump(self.myTableViewDataSource)
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
}
}
}
catch{
}
}
}
task.resume()
}//End func

Okey, so with Alamofire + SwiftyJSON, you can do this:
func loadList(){
let url = "https://jsonplaceholder.typicode.com/photos"
AF.request(url).responseJSON { (response) in
switch response.result {
case .success(let value):
let json = JSON(value)
print(json)
for value in json.arrayValue {
let url = value.dictionaryValue["url"]!.stringValue
let albumId = value.dictionaryValue["albumId"]!.stringValue
let thumbnailUrl = value.dictionaryValue["thumbnailUrl"]!.stringValue
let id = value.dictionaryValue["id"]!.stringValue
let title = value.dictionaryValue["title"]!.stringValue
// Add this album to array.
let album = AlbumModel(id: id, albumId: albumId, title: title, thumbnailUrl: thumbnailUrl)
albums.append(album)
}
case .failure(let error):
print(error)
}
}
}
EDIT:
I made model for values
class AlbumModel {
var id: String?
var albumId: String?
var title: String?
var thumbnailUrl: String?
init(id: String?, albumId: String?, title: String?, thumbnailUrl: String?){
self.id = id
self.albumId = albumId
self.title = title
self.thumbnailUrl = thumbnailUrl
}
}
After that, just create an array like var albums = [AlbumModel]() and you can append all the albums to this. Easy to use after in tableViewcell (example: albums[indexPath.row].id)
