swift - Swift 错误“类型‘BookingDataModel’不符合协议‘Decodable’”

问题描述

我想让我的应用程序的某些部分离线，因为我的客户要求它。我一直在努力使我的结构可编码，以便我可以将数据保存到用户默认值，但我总是收到这个错误

类型“BookingDataModel”不符合协议“Decodable”

这是我的 BookingDataModal：

struct BookingDataModel: Codable {

    static var shared = BookingDataModel()

    var collaps = false
    var _id = ""
    var userId = ""
    var venderName = ""
    var created_at = ""
    var transaction_id = ""
    var payment_method = ""
    var updated_at = ""
    var booking_confirmed = false
    var booking_status = ""
    var payment_status = false
    var type = ""
    var isCanceledRequest: Bool?

    var flight: [FlightBookingDataModel]?
    var newFlight: (departure: [FlightBookingDataModel], return: [FlightBookingDataModel])?
    var event: HotelBookingDataModel?
    var hotel: NewHotelBookingDataModel?//HotelBookingDataModel?

    var isAxaPolicy = false
    var relationshipId = ""
    var passengers = [UsersModel]()
    var total = 0.0
    var tacCoinDiscount: Int?
    var couponDiscount: Int?
    var afterDiscountAmount: Int?

     func getBookingDataModel(arr: NSArray, type: String) -> [BookingDataModel] {
    // save data from API
    }
    }

起初我认为我的其他模式不可编码，所以我将它们全部设为可编码，它仍然会抛出相同的错误这是 FlightBookingDataModal ：

struct FlightBookingDataModel: Codable {

    static var shared = FlightBookingDataModel()

    var pnrData = PNRDataModel()
    var src_name = ""
    var dst_name = ""
    var srcCode = ""
    var dstCode = ""

    var atime_utc = String()
    var dtime_utc = String()
    var atime = String()
    var dtime = String()

    var flight_no = ""
    var checkin = ""
    var price = 0.0
    var airLineName = ""
    var eticket_link = ""
    var invoice = ""
    var isReturnFlight = false

    func getFlightBookigDataModel(dict: NSDictionary) -> [FlightBookingDataModel] {
    // Save data from API
    }
    }

PNR 模式：

class PNRDataModel: Codable  {
  var src = ""
  var dst = ""
  var iata = ""
  var pnr = ""
  }

酒店预订数据模型：

struct HotelBookingDataModel: Codable {

    var cityName = ""
    var name = ""
    var address = ""
    var startOfServiceTime = ""
    var endOfServiceTime = ""
    var aetherReference = ""
    var provider = ""
    var reference = ""
    var price = 0.0
    var date = ""
    var reservationId = ""
    }

新酒店预订数据模型：

struct NewHotelBookingDataModel: Codable {
    var name = ""
    var address = ""
    var cityName = ""
    var price = 0.0
    var reference = ""
    var provider = "" //not found in new response
    var startOfServiceTime = ""
    var endOfServiceTime = ""
    var aetherReference = ""
    }

如果有人可以给我任何见解，说明为什么这不起作用，那将对我有很大帮助。我只想在有限的时间内离线保存 [BookingDataModal]，直到用户重新上线。
