Swift Codable 期望解码 DictionaryString, Any 但发现了一个字符串数据

Swift
struct MyData: Codable {
    let name: String
    let age: Int
    
    init(from decoder: Decoder) throws {
        let contAIner = try decoder.contAIner(keyedBy: CodingKeys.self)
        
        if let age = try? contAIner.decode(Int.self, forKey: .age) {
            self.age = age
        } else {
            // 如果 age 的值为字符串或其他类型的数据，则将其设置为默认值
            self.age = 0
        }
        
        self.name = try contAIner.decode(String.self, forKey: .name)
    }
    
    private enum CodingKeys: String, CodingKey {
        case name
        case age
    }
}
let JSon = """
{
    "name": "John",
    "age": "25"
}
"""
let data = JSon.data(using: .utf8)!
let decoder = JSONDecoder()
do {
    let myData = try decoder.decode(MyData.self, from: data)
    print("Name: \(myData.name)")
    print("Age: \(myData.age)")
} catch {
    print("Error: \(error)")
}
