Различные контроллеры представления загружают один и тот же текст

Question

Я новичок в программировании и быстром программировании в целом, и я пытаюсь создать приложение для викторины, и я хочу, чтобы приложение переместилось с начального экрана в меню выбора s, а затем на экран викторины.

Проблема в том, что когда я нажимаю кнопку второй категории, она приводит меня к правильному контроллеру вида.Но он выводит те же вопросы и ответы из первого массива.Я пытался сделать переменные и массивы приватными, но это все равно не сработало.

Что я делаю не так?
