I want to make generic specially "WeekDays.CodingKeys
struct WeekDays : Codable {
var sunday : String?
// this is coding Keys
enum CodingKeys: String, CodingKey {
case sunday = "sunday"
}
// this is decoder method
init(from decoder: Decoder) throws {
let values = try decoder.container(keyedBy: CodingKeys.self)
sunday = checkDataValue(values: values, str: .sunday)
}
// this method for convert each and every value string
mutating func checkDataValue(values: KeyedDecodingContainer<WeekDays.CodingKeys>, str: CodingKeys) -> String {
var strData = String()
do {
strData = (try values.decodeIfPresent(String.self, forKey: str))!
}
catch {
do {
let intStrData = (try values.decodeIfPresent(Int.self, forKey: str))!
strData = "(intStrData)"
}
catch {
do {
let doubleStrData = (try values.decodeIfPresent(Double.self, forKey: str))!
strData = "(doubleStrData)"
}
catch {
strData = ""
}
}
}
return strData
}
}
// I want to make generic specially "WeekDays.CodingKeys"
mutating func checkDataValue(values: KeyedDecodingContainer, str: CodingKeys) -> String
