Trouble parsing JSON data into Swift

Question

i am trying to parse JSON data from web service into my Swift

JSON Output on my web browser:

 [{"code":0,"message":"Check Username and Password....","userid":""}]

Swift Code:

  Alamofire.request(URL_USER_LOGIN, method: .post, parameters: parameters).responseJSON

    {
    response in
    //printing response
    print(response)

    if let userJSON = response.result.value
    {
        let userdata:Dictionary = userJSON as! Dictionary<String, Any>
        let message:Dictionary = userdata["message"] as! Dictionary<String, Any>

        print(message)


    }

I want to use message element from the JSON for my code. However i get the following output and error:

    (
    {
    code = 1;
    message = "Login Successfull";
    userid = 236;
}
)
     Could not cast value of type '__NSSingleObjectArrayI' (0x10fd94b98) to 'NSDictionary' (0x10fd958b8).

   Could not cast value of type '__NSSingleObjectArrayI' (0x10fd94b98) to 'NSDictionary' (0x10fd958b8).

How do I successfully get the value of message and print? Can someone please show me the correct code for my case. Thanks in advance!

Rather than changing the Swift code (you have to change the type of `message` anyway) a more efficient solution is to change the php code on the server to send a dictionary. — vadian, Nov 03 '18 at 16:50

It's an array not dictionary

if let userdata = userJSON as? [[String:Any]] { 
   if let message = userdata[0]["message"] as? String {
      print(message)
   }
}
