copié la prueba de accesibilidad de apple, pero el enlazador da una falla

Question

intenté usar el proyecto de accesibilidad publicado por apple para detectar una accesibilidad en un ejemplo propio. i copiado el más inicialización, pero consigo este fracaso en el enlazador:

olvidarlo. Simplemente no sabía que tenía que agregar el marco de configuración del sistema de forma manual. Pensé que se agregaría cuando se importó.
