Как вы справляетесь с загадочными символическими сбоями в ваших приложениях для iOS? ⇐ IOS

[Anonymous]

В моем приложении произошло 1–3 сбоя, которые кажутся редкими состояниями гонки. На данный момент они произошли с несколькими сотнями моих пользователей. Я не могу их воспроизвести и понятия не имею об их причине. Например:

Нет никаких ссылок на какой-либо конкретный мой код — вообще никаких подсказок.
AFAIK, я следую лучшим практикам, таким как манипулирование SwiftUI. состояние только в основном потоке, используя актеров там, где это необходимо, и т. д.
Какова правильная стратегия для расследования и устранения таких ошибок? Как Apple ожидает, что мы с ними справимся? Они кажутся совершенно бездействующими.
