Mostrar alertas

Si quieren tener un teclado con el boton aceptar y que cuando terminen de escribir y presionen aceptar (para no tener que presionar siempre el icono de lupa y mejorar la UX) ejecute la función de buscar la palabra que acaba de escribir, escriban el siguiente código al final del textfield

Creo que como parte de la clase también seria bueno que mostraran como refactorizar correctamente el código en vistas individuales ✌️
