+/* las excepciones se usan para manejar errores  en swift 
+   se pueden manejar de la siguiente manera
+   do {
+    
+   } catch error {
+    
+   }
+    las funciones , clases pueden tener excepciones para agregar alguna 
+    se hace de la siguiente manera:
+
+    func getResponde() throws  ->String
+
+    esto quiere decir que la funcion puede retornar un error
+
+    para crear uno o mas errores personalizados usamos el enum este debe implementar el protocolo Error
+
+    enum MiError: Error {
