在过去的几天里，我一直试图解码一个JSON文件，通过一个uikit应用程序，但不断失败，无论我试图这样做。有人能帮我吗？
这是我的解码函数：

override func viewDidLoad() {
        super.viewDidLoad()
        cidadelabel.text = city!
        downloadJSON {
            print("success")
        }
        print(result.main?.temp!)
        // var temperatura = result?.main?.temp
        // temperatura = temperatura! - 273.15
        // temperatureLabel.text = "\(String(temperatura!))°C"
    }
    
    func downloadJSON(completed: @escaping () -> ()){
        let url = URL(string: "https://api.openweathermap.org/data/2.5/weather?appid=******d&q=" + city!)
        URLSession.shared.dataTask(with: url!) {
            data, response, error in
            if error == nil{
                do{
                    print(data!)
                    print(response!)
                    
                    self.result = try JSONDecoder().decode(Response.self, from: data!)
                    
                    DispatchQueue.main.async {
                        completed()
                    }
                }
                catch {
                    print("error fetching data from the api")
                    print(String(describing: error))
                }
            }
        }.resume()
    }

这是我的类接收JSON：

import Foundation

struct Response: Codable {
    
    var coord: Coord?
    var weather: [WeatherBase]?
    var main: Main?
    var visibility: Int?
    var wind: Wind?
    var rain: Rain?
    var clouds: Clouds?
    var dt: Int?
    var sys: Sys?
    var timezone: Int?
    var id: Int?
    var name: String?
    var cod: Int?

}

struct Coord: Codable {
    var lon: Double?
    var lat: Double?
}

struct WeatherBase: Codable {
    var id: String { _id! }
    private var _id: String?
    var base: String?
    
    mutating func prepare() {
        _id = _id ?? UUID().uuidString
    }
}

struct Weather: Codable {
    var id: Int?
    var main: String?
    var description: String?
    var icon: String?
}

struct Main: Codable {
    var temp: Double?
    var feels_like: Double?
    var temp_min: Double?
    var temp_max: Double?
    var pressure: Int?
    var humidity: Int?
}

struct Wind: Codable {
    var speed: Double?
    var deg: Int?
}

struct Rain: Codable{
    var umh: Int?
}

struct Clouds: Codable {
    var all: Int?
}

struct Sys: Codable {
    var type: Int?
    var id: Int?
    var country: String?
    var sunrise: Int?
    var sunset: Int?
    
}

这是JSON：

{"coord":{"lon":-35.7353,"lat":-9.6658},"weather":[{"id":801,"main":"Clouds","description":"few clouds","icon":"02d"}],"base":"stations","main":{"temp":302.84,"feels_like":305.59,"temp_min":302.84,"temp_max":302.84,"pressure":1011,"humidity":61},"visibility":10000,"wind":{"speed":7.2,"deg":90},"clouds":{"all":20},"dt":1672689129,"sys":{"type":1,"id":8413,"country":"BR","sunrise":1672646788,"sunset":1672692412},"timezone":-10800,"id":3395981,"name":"Maceió","cod":200}

响应是告诉我，一切都是零（可选），因为它是从API得到一个不同的结果，这是没有意义的原因，当我进入相同的链接给我正确的JSON
