As part of a rewrite from a C++ codebase, I have a class with an array of any V, where V extends Codable. How can I create the required init and encode functions here?

import Foundation

protocol V: Codable {
 // some methods
}

// some other classes implementing V

class T: V {
    var elements: [any V]

    private enum CodingKeys: String, CodingKey {
        case elements
    }
    
    required init(from decoder: Decoder) throws {
        let container: KeyedDecodingContainer<T.CodingKeys>
            = try decoder.container(keyedBy: CodingKeys.self)
        self.elements = try container.decode([any V].self, forKey: .elements)
    }

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

Thanks in advance
