问题描述
我展示了一个带有 UIHostingController 的 SwiftUI 视图，作为 MapKit 注释的 detailAccessoryView 的一部分，它工作正常，在测试时从未崩溃，但现在它已部署到生产中，一些用户报告了崩溃。目前我无法重现崩溃，但这是我看到不同用户重复出现的崩溃报告：

为了显示注释视图的 detailAccessoryView，我使用了一个包装 UIView，其中包含显示 SwiftUI 视图的 UIHostingController。在代码的这一点上，我在包装器 UIView 中调用 layoutIfNeeded()，以便正确调整视图的大小。我不确定这是否弄乱了布局系统。我自己无法重现这个问题，所以我无法真正测试这个理论。
有人可以对此有所了解吗？这是我第一次在生产环境中部署 SwiftUI 代码，所以我不确定如何阅读这些崩溃报告，甚至不确定这里可能发生的事情。
更新：
能够对崩溃报告的其余部分进行符号化，包括 SwiftUI 符号。那里似乎有对 AG::precondition_failure 的引用。
这是更好的版本：
