My classes

    let results: [Results]
}

struct Results: Codable  {
    let smallDescription: String
    let price: Price
    let gallery: [ImageHotel]
    let name: String
    let address: Address

    var getRandonImage: ImageHotel {
        let index = Int(arc4random_uniform(UInt32(gallery.count)))
        return gallery[index]
    }
}

My manager

class func getHotels(onComplete: @escaping (HotelData?) -> Void) {
        AF.request(path).responseJSON { (response) in
            guard let jsonData = response.data else { return }
            guard let hotelData = try? JSONDecoder().decode(HotelData.self, from: jsonData)
                else {
                    onComplete(nil)
                    return
            }
            onComplete(hotelData)
            return
        }
    }
}

==============

Cell

func prepareCell(with hotel: Results){
        lbName.text = hotel.name
        lbSmallDescription.text = hotel.smallDescription
        lbPrice.text = "R$ \(hotel.price.amount)"
        lbAdress.text = hotel.address.city
    }

==============

TableView class HotelTableViewController: UITableViewController {

            var hotels: [Results] = []
            let hotelManager = HotelManager()

            override func viewDidLoad() {
                super.viewDidLoad()
                loadHotels()
            }


            override func viewWillAppear(_ animated: Bool) {
                super.viewWillAppear(animated)

            }


            override func numberOfSections(in tableView: UITableView) -> Int {
                return 1
            }


            override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
                return hotels.count

            }


            override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
                let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! HotelTableViewCell
                let hotel = hotels[indexPath.row]
                cell.prepareCell(with: hotel)
                return cell
                }


            func loadHotels() {
                HotelManager.getHotels { (hotelData) in
                    if let hotelData = hotelData {
                        self.hotels += hotelData.results
                    }
                }
            }

        }

Answer 1

Your direct issue is that you need to call reloadData() if you want your UITableView to look at your downloaded data and load the appropriate cells. You can put in the completion handler of your network call, or in a didSet on your hotels property.

Additionally, you shouldn't use responseJSON for Decodable types, it's redundant. Instead you should use responseDecodable and pass the type you want to parse: responseDecodable(of: HotelData.self) { response in... } .
