iOS 仅在 iOS 12 台设备上从 App Store 下载时，应用程序在启动时崩溃
iOS app crashes on launch when only when downloaded from App Store on iOS 12 device
我有一个 iOS 应用程序，它在所有设备上都运行良好，除非它们使用 iOS 12。我不确定问题出在哪里。我尝试直接从我的笔记本电脑下载该应用程序，它运行良好。但是，当它从 App Store 或 TestFlight 下载时，它会在启动时崩溃。
这是我的崩溃日志：

我在应用程序第一次启动时序列化了一个大型 Realm 数据库。这是导致问题的原因吗？我没有办法知道，因为当我通过我的电脑安装应用程序时不会发生这种情况。
8badfood是看门狗定时器异常。您必须尽快退出 didFinishLaunching 并显示视图。
如果您必须加载大量数据，那么您应该提供初始 "loading" 视图并执行加载，完成后移至实际的 UI。
这是为了避免给用户留下应用刚刚 "hung".
的印象
您只在 iOS 12 台设备上遇到崩溃的事实可能是因为它们是较旧、较慢的设备。
