json - タイプ ' ' はプロトコル 'エンコード可能' に準拠していません

Question

誰かがここで何が悪いのか教えてもらえますか?

このエラーが送信されます：タイプ「CityWeatherInfo」はプロトコル「エンコード可能」に準拠していません

struct CityWeatherInfo: Codable {
   var name: String
   var main: Main
   var weathers: [Weather]

   private enum CodingKeys: String, CodingKey {
       case weathers = "weather"
       case main = "main"
       case name

   }
   init(from decoder: Decoder) throws {
       let container = try decoder.container(keyedBy: CodingKeys.self)
       self.name = try container.decode(String.self, forKey: .name)
       let mainContainer = try container.nestedContainer(keyedBy: CodingKeys.self, forKey: .main)
       let weatherContainer = try container.nestedContainer(keyedBy: CodingKeys.self, forKey: .weathers)
   }
}

struct Weather: Decodable {
   var main: String
   var description: String

   private enum WeatherKeys: String, CodingKey {
       case main = "main"
       case description = "description"
   }
}

struct Main: Decodable {
   var temp: Double
   var feels_like: Double
   var temp_min: Double
   var temp_max: Double

   private enum MainKeys: String, CodingKey {
       case temp = "temp"
       case feels_like = "feels_like"
       case temp_min = "temp_min"
       case temo_max = "temp_max"
   }
}

Jsonはこれです：
