Приветствую.

Реализовал в своем проекте Expanded TableView Cells по уроку :
https://swiftbook.ru/post/tutorials/expanded-tableview-cells/

Но всегда рандомно вылетает ошибка EXC_BAD_ACCESS :

Перебровал уже все, ни чего не помогает. Каждый раз ошибка в tableView.reloadSections([section], with: .automatic) и delegate?.expandedSection(button: sender)


#2

Решено путем замены reloadSections на reloadData, пожертвовав анимацией.
Но все равно интересно, почему возникала эта ошибка, у кого какие мнения?
