Serializing keys in JSON using Swift

I am working on trying to serialize a JSON string. This one:

"user": {
    apellidos = "Vasco Fornas";
    "created_at" = "<null>";
    email = "[email protected]";
    "id_usuario" = 122;
    imagen = "1ufm2Fmifoto.jpeg";
    name = "";
    "nivel_usuario" = 1;
    nombre = Modesto;
    unidad = 0;
    "updated_at" = "<null>";
}, "uid": , "error": 0]
{
    apellidos = "Vasco Fornas";
    "created_at" = "<null>";
    email = "[email protected]";
    "id_usuario" = 122;
    imagen = "1ufm2Fmifoto.jpeg";
    name = "";
    "nivel_usuario" = 1;
    nombre = Modesto;
    unidad = 0;
    "updated_at" = "<null>";
}

And this is my code so far:

do {//creamos nuestro objeto json                
  print("recibimos respuesta")

  if let json = try JSONSerialization.jsonObject(with: data) as? [String:Any] { //Any for, Any data type

    //Do with json
    print(json);

    DispatchQueue.main.async {//proceso principal             
      let mensaje = json["user"]
      print(mensaje!);                      
    }
  }
}

The first print shows the complete JSON string, and the second print shows the item "user"

How could I get the values for all keys under "user" item?

you can try this, eg:

if let mensaje = json["user"] as? [String:String] {
    for key in mensaje.keys {
        let currentValue = mensaje[key] as? String ?? "" // cast whatever you like
        print(currentValue)
    }
}

or getting values as array...

if let mensaje = json["user"] as? [String:String] {
    let yourValues = Array(mensaje.values)
    print(yourValues)
}

if you are searching for "apellidos":

var apellidos?
if let mensaje = (json["user"] as? [String:String]) {
    apellidos = mensaje["apellidos"] as? String ?? ""
}
print(apellidos)
