是否使具有关联值的枚举符合可解码？

enum MyEnum: Codable {
    case optionA(Int)
    case optionB(String)
    
    // 实现编码方法
    func encode(to encoder: Encoder) throws {
        var container = encoder.container(keyedBy: CodingKeys.self)
        
        switch self {
        case .optionA(let value):
            try container.encode(value, forKey: .optionA)
        case .optionB(let value):
            try container.encode(value, forKey: .optionB)
        }
    }
    
    // 实现解码方法
    init(from decoder: Decoder) throws {
        let container = try decoder.container(keyedBy: CodingKeys.self)
        
        if let value = try container.decodeIfPresent(Int.self, forKey: .optionA) {
            self = .optionA(value)
        } else if let value = try container.decodeIfPresent(String.self, forKey: .optionB) {
            self = .optionB(value)
        } else {
            throw DecodingError.dataCorruptedError(forKey: .optionA, in: container, debugDescription: "Invalid data")
        }
    }
    
    // 定义编码和解码的键
    enum CodingKeys: String, CodingKey {
        case optionA
        case optionB
    }
}
