如何使ObservableObject符合可编码协议？

import SwiftUI

class MyObject: ObservableObject, Codable {
    @Published var name: String
    @Published var age: Int

    enum CodingKeys: String, CodingKey {
        case name
        case age
    }

    init(name: String, age: Int) {
        self.name = name
        self.age = age
    }

    required init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        name = try container.decode(String.self, forKey: .name)
        age = try container.decode(Int.self, forKey: .age)
    }

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

struct ContentView: View {
    @ObservedObject var myObject = MyObject(name: "John", age: 25)

    var body: some View {
        Text("Name: \(myObject.name), Age: \(myObject.age)")
    }
}
