Я включил Address Sanitizer -> Detect use of stack after return в схеме запуска.Затем я запустил приложение на iPad из Xcode напрямую, и оно заработало.Затем я закрыл приложение, которое завершило сеанс отладки.Затем я запустил приложение, но приложение продолжает падать.Журнал сбоев приведен ниже.
