Я выполнял шаг учебника «Построить свое второе приложение iOS» для шага, и я столкнулся с этой ошибкой после того, как учебник пообещал, что все ошибки исчезнут, но ошибка не появлялась до тех пор, покавсе другие ошибки были исправлены, и я попытался скомпилировать его.
Ошибка:
The document "MainStoryboard_iPhone.storyboard" could not be opened. Failed to unarchive element named "UITableViewController".
Вот ссылка на учебник .
Вот моя раскадровка в формате XML

Я совершенно новичок в цели c и Xcode, поэтому я не уверен, что делаю неправильно или даже вообще, с чего начать с такой ошибки.Если кто-то знает, как исправить эту ошибку, или лучший (онлайн) ресурс для одновременного изучения цели c и разработки под iOS, я был бы очень признателен за любую из них.
Здесь - этомой проект, если кто-то хочет взглянуть на него для меня.
