Я нахожусь в стадии бета-тестирования, и на данный момент 5 пользователей полностью успешно вошли в систему и работают с приложением. Однако информация о 3 пользователях Facebook не сохраняется в Parse, и приложение вылетает, когда они пытаются перейти в виртуальную среду, которая загружает профиль пользователя. Я не понимаю, что происходит. Вот мой код входа, он покажется очень дилетантским и грязным, так что заранее извиняюсь! (Новичок, но пытается) Делегат приложения:

Получил пароли facebook от пользователя, который не работал, и попытался войти в систему с помощью xcode и подключенного телефона, получил эту ошибку:
