Answer 1

Если это происходит последовательно примерно в одном и том же месте в вашем коде, то Похоже, вы обнаружили внутреннюю ошибку в компиляторе, и я думаю, что лучший способ продолжить - сначала отправить ее в виде сообщения об ошибке в apple (URL-адрес указан в вставленном вами результате).

И затем, если вы хотите продолжить, попробуйте внести изменения в код, который вы пытаетесь скомпилировать, например закомментировать первую половину, затем повторите, затем закомментируйте вторую половину и повторите попытку. Это должно указывать на код, вызывающий внутреннюю ошибку компилятора.

Иногда переупорядочение некоторого кода решит проблему для вас. Так что, по крайней мере, вы можете продолжать развиваться.
