我在 TestFlight 中的应用程序在启动时有几次崩溃，当它决定崩溃时，它会在之后的每次启动时都这样做。修复它的唯一方法是重新安装应用程序，然后在将来它会再次崩溃，所以我不知道如何重现崩溃。
我有崩溃日志，但我不确定要从中读取什么内容。该应用程序是纯 SwiftUI。

我遇到了同样的问题。它是由 WKWebView 的 AnyView 和 NSViewRepresentable 包装器的组合引起的。通过使用@ViewBuilder 重写辅助函数来摆脱 AnyView 解决了该问题。
问题：
func viewFunc() -> AnyView {
switch self {
case .case1: return AnyView(ListOfWebViewWrappers())
default: return AnyView(WaitView())
}
}
解决方案：
@ViewBuilder
func viewFunc() -> some View {
switch self {
case .case1: ListOfWebViewWrappers()
default: WaitView()
}
}
@ViewBuilder 允许 SwiftUI 正确跟踪每个视图的身份并正确管理资源。有关视图标识的更多信息：https://developer.apple.com/videos/play/wwdc2021/10022/
