Здравствуйте!
Делаю простое приложение To-Do list (задание из книги Objective-C Programming: The Big Nerd Ranch Guide) и возникла проблема с сохранением документа. Все остальное работает вполне корректно.
При попытке сохранить появляется ошибка (сохранение должно происходить на диск, без использования iCloud)

К сожалению нагуглить ничего не удалось, штудирование документации так же ничего не дало, буду благодарна за любой совет.
Заранее спасибо!
Простой
