Мы разработали мобильное приложение Xamarin Forms 4.6. Приложение отлично работает на Android, но случайно вылетает на iOS. Журнал сбоев вылетает случайным образом при одной и той же функции:

Вы можете сначала обновить версию XF до последней (4.8.x), чтобы проверить, существует ли проблема. — person manishKungwani schedule 27.11.2020
@ LucasZhang-MSFT с v4.8 у нас возникла проблема с UIWebView, из-за которой Apple AppStore отклонил приложение. — person manishKungwani schedule 27.11.2020
Проверьте stackoverflow.com/questions/64369632/ — person manishKungwani schedule 27.11.2020
@ LucasZhang-MSFT Это было сделано. Таким образом, проблема была связана с кодом пользовательского интерфейса, работающим в фоновом потоке. Он работает на всех версиях iOS, кроме 14.2, где происходит случайный сбой. Любое мнение по этому поводу — developer.apple.com/forums/thread/666399 — person manishKungwani schedule 27.11.2020
@manishKungwani Вы символизировали крушение? — person manishKungwani schedule 27.11.2020
@ LucasZhang-MSFT в фоновом потоке был код пользовательского интерфейса, мы исправили эту проблему, и теперь эти сбои происходят только в iOS 14.2 — developer.apple.com/forums/thread/666399. Какая-нибудь помощь возможна с этим? — person manishKungwani schedule 28.11.2020
@SushiHangover Это упрощенные журналы сбоев. — person manishKungwani schedule 28.11.2020
