Вопрос:
У меня есть приложение для отслеживания тренировок, написанное на SwiftUI. Не вдаваясь в подробности кода, поскольку я даже не знаю, в какой части кода проблема, он использует CoreLocation для получения обновлений местоположения и использует CoreData для сохранения данных, связанных с местоположением. Кажется, что пока оно работает на переднем плане, все в порядке, но через 40-60 минут работы в фоновом режиме оно выходит из строя. Когда я читаю журналы, я вижу приведенный ниже журнал. Я не могу понять из журнала, где в моем коде я должен искать решение? Какое действие я предпринимаю в фоновом режиме, которое требует слишком большой мощности процессора, это сохранение в CoreData? Предполагается, что все обновления пользовательского интерфейса автоматически приостанавливаются, поскольку приложение работает в фоновом режиме, верно? Можете ли вы увидеть что-нибудь в журнале, что может дать мне некоторый намек на то, в чем проблема.
Я видел эту страницу в Apple: https://developer.apple.com/library/archive/documentation/Performance/Conceptual/EnergyGuide-iOS/WorkLessInTheBackground.html раздел «Устранение сбоев фонового приложения», но я не вижу вещей, на которые там есть ссылки в журнале. Можете ли вы? Есть предложения, как я могу определить проблему?

1. Не могли бы вы предоставить свой код для этого?
2. Я был бы рад, но не знаю, какая часть кода. Я надеялся, что кто-нибудь сможет прочитать немного больше в журнале выше, чтобы мы могли сосредоточиться на некоторой части кода, которая может быть проблематичной.
3. Обозначение
11 ??? (OutdoorWorkout 138608) [0x100795d70— Я предполагаю, что это ваша часть.4. Спасибо, позвольте мне выяснить, почему это не обозначено, и, надеюсь, обозначим это и вернемся к вам с обновлениями. Я использовал один Mac и один iPhone и встроил его из Xcode в iPhone, поэтому не уверен, почему это еще не обозначено.
5. @Asperi Вы знаете, почему мои журналы сбоев не обозначены символами? Я подключил свой iPhone к своему Mac и встроил приложение в свое устройство из Xcode. Я думал, что это должно быть автоматически обозначено символом. Я не думаю, что я изменил какие-либо настройки по умолчанию. Все шаги, которые говорят о символизировании отчетов о сбоях, относятся к сборкам, которые отправляются в App Store.
