parsing Json in swift4

Question

hello i try to decode Json:

{"result":[ {"ID":"80", "time":"09:00:00", "status":[ {"status":0,"kirpeja_id":"74","name":"Natalja","image":"natalija255.png","duration":"00:20:00"}, {"status":1,"kirpeja_id":"80","name":"Lina","image":"kazkas.png","duration":"00:30:00"}, {"status":0,"kirpeja_id":"82","name":"Rasa ","image":"IMG_20170906_171553.jpg","duration":"00:40:00"} ]}, {"ID":"81", "time":"09:10:00", "status":[ {"status":0,"kirpeja_id":"66","name":"Ilona","image":"ilona_new.jpg","duration":"00:30:00"}, {"status":0,"kirpeja_id":"74","name":"Natalja","image":"natalija255.png","duration":"00:20:00"}, {"status":0,"kirpeja_id":"80","name":"Lina","image":"kazkas.png","duration":"00:30:00"}, {"status":0,"kirpeja_id":"82","name":"Rasa ","image":"IMG_20170906_171553.jpg","duration":"00:40:00"} ]}, ...

here my classes

class TimeStatusResult: Codable {
let result: [TimeStatus]
init (result:[TimeStatus]) {
self.result = result
}
}
class TimeStatus: Codable {
let ID:String?
let time: String?
let status: [Status]
init (status:[Status]) {
    self.ID = ""
    self.time = ""
    self.status = status
}
}
class Status: Codable {
let status: String?
let kirpeja_id: String?
let name: String?
let image: String?
let duration: String?
init () {
    self.status = ""
    self.kirpeja_id = ""
    self.name = ""
    self.image = "nophoto.jpg"
    self.duration = ""
}
}

here my json function

final let jsonUrl = URL(string: "http://**********/getlaikas_new.php")
private var timeStatusResult = [TimeStatus]()

 func downloadJson () {
    guard let downloadURL = jsonUrl else {return}
    var request = URLRequest(url: downloadURL)
    request.setValue("application/x-www-form-urlencoded",forHTTPHeaderField: "Content-Type")
request.httpMethod = "POST"
    let postString = "data=\(pInfo.paslaugosData!)&salonId=\(pInfo.ID!)&paslaugos_id=\(pInfo.paslaugosId!)"
    request.httpBody = postString.data(using: .utf8, allowLossyConversion: true)
    URLSession.shared.dataTask(with: request) {data, urlResponse, error in

        guard let data = data , error == nil, urlResponse != nil else {
            print ("something wrong")
            return }
        print ("downloaded!")
        do
        {
            let decoder = JSONDecoder()
            print (data)
            let downloadedTimeStatus = try decoder.decode(TimeStatusResult.self, from: data)

            self.timeStatusResult = downloadedTimeStatus.result

            DispatchQueue.main.async {
               // self.kirpejosPaslaugosTable.reloadData()
            }

        } catch {
            print ("something wrong after download")
        }
        }.resume()
}

in this line i have issue

let downloadedTimeStatus = try decoder.decode(TimeStatusResult.self, from: data)

somebody can help me? :(

The error is very clear:

...burzua_1. Status.(CodingKeys in _479ABD1AF7892C9F2FD23EC23214E088). status ], debugDescription: " Expected to decode String but found a number instead. "

The value for key status is not in double quotes so it's an Int

class Status: Codable {
   let status: Int
   ...

Please don't declare all properties carelessly as optional. For example status as well as all other keys is present in all Status dictionaries.
