I want to decode this JSON to a normal-looking Struct or Class but I'm facing a problem that I need to create a whole new Struct for property age, how can I avoid that and save age Directly to class Person?
Also, it would be good to convert Int to String
{
"name": "John",
"age": {
"age_years": 29
}
}
struct Person: Decodable {
var name: String
var age: Age
}
struct Age: Decodable {
var age_years: Int
}
I want to get rid of Age and save it like:
struct Person: Decodable {
var name: String
var age: String
}
CodePudding user response:
You can try
struct Person: Decodable {
let name,age: String
private enum CodingKeys : String, CodingKey {
case name, age
}
init(from decoder: Decoder) throws {
let container = try decoder.container(keyedBy: CodingKeys.self)
name = try container.decode(String.self, forKey: .name)
do {
let years = try container.decode([String:Int].self, forKey: .age)
age = "\(years["age_years"] ?? 0)"
}
catch {
let years = try container.decode([String:String].self, forKey: .age)
age = years["age_years"] ?? "0"
}
}
}
