Ошибки Xcode beta 6

Для всех, кто имеет подобные проблемы в Bata 6. Я решил это, удалив содержимое в/Users/[ваше имя пользователя]/Library/Developer/Xcode/DerivedData, как можно увидеть в этом сообщении Внезапно возникает сбой компилятора "arrayForceCast" в Swift XCode beta 6

Оригинальное сообщение:

Я только что установил Xcode beta 6 и получаю очень необычные ошибки. Я не могу понять, кто они.
