ios - 在 json 响应 swift 嵌套循环中循环

Question

我有这个 JSON 响应:

{
    "success": false,
    "message": {
       "gender": [
           "The gender field is required."
       ],
       "sms_token": [
           "The sms token field is required."
       ]
   }
}

注意消息对象可以有两个以上的元素...

我正在尝试获取消息对象中的数组...我试过这个:

guard let messages = receivedTodo["message"] as? String, let message = receivedTodo["sms_token"] as? String else {
                    print("Could not get messages from JSON")
                    return
                }
                print("The error is:" + message)
            }

但这没有用，我总是会收到“无法从 JSON 获取消息”...

我想循环并获取消息对象中的所有元素并将它们打印出来。如何存档？

guard let messages = receivedTodo["message"] as? [String:Any],let tokens = messages["sms_token"] as? [String], let genders = messages["gender"] as? [String] else {  
    return
} 
for token in tokens {
      print(token)
}
for gender in genders {
      print(gender)
}
