Below, I have a codable class that I'm able to connect Published variables with the purpose of converting them to Json and sending an API (API is out of scope). I have these two variables connected in the app to a toggle and picker which I can print out the values print(user.age) etc.. when a button is pressed but.. now, I'd like a way to save this data in json format so I can print out both var's in json format (pretty printed) in the console when the button is pressed. Thanks!

class User: ObservableObject, Codable {
    enum CodingKeys: CodingKey {
        case disabled
        case age
    }

    init() { }

    required init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        disabled = try container.decode(Bool.self, forKey: .disabled)

        age = try container.decode(Int.self, forKey: .age)
    }

    func encode(to encoder: Encoder) throws {
        var container = encoder.container(keyedBy: CodingKeys.self)
        try container.encode(disabled, forKey: .disabled)
        try container.encode(age, forKey: age)
    }

    @Published var disabled: Bool = false
    @Publisehd var age: Int = 18
}

    @StateObject var user = User() // Connects to the Class.

Does this help…

    let encoder = JSONEncoder()
    encoder.outputFormatting = .prettyPrinted

    do {
        let data = try encoder.encode(user)  //convert user to json data here
        print(String(data: data, encoding: .utf8)!)   //print to console
    } catch {
        print("fail")
    }
