我有一个在生产和 Testflight 中运行良好的应用程序。但是，最近我们的客户升级到 iOS 15，应用程序在启动时开始崩溃。我对此进行了调查，并能够通过直接部署到设备来重现崩溃。崩溃的原因最终与我们使用的 Microsoft AppCenter Crash Analytics Nuget 包有关。该问题与一些受 iOS 保护的命名空间有关，被 Microsoft Analytics 包使用。修复只是升级软件包，在部署到设备后，我不再能够重现崩溃。
但是，当我将构建上传到 Testflight 时，应用程序在启动时仍然崩溃。由于我无法调试甚至无法通过启动画面，因此我无法获得任何有用的日志或崩溃报告。我有 iOS 崩溃日志，但它不是特别有用，因为没有回溯。无论如何，我都会在这里发布崩溃，以防有人能理解它。
从那以后，我尝试了很多方法来尝试解决这个问题。其中之一是从项目中完全删除 MS Analytics 包。另一个是将我的应用程序中的所有 nuget 包升级到最新版本。
有旧版本的应用程序不会在 Testflight 上崩溃，但是当我将代码恢复到这些版本提交并构建/上传到 Testflight 时，这些新版本在启动时会崩溃。这让我相信我的构建设置有问题（我使用连接到 Mac 的 Windows 机器来构建）。但是，我可以使用相同的设置构建其他不会崩溃的应用程序。我很茫然！我很难相信这是与我已经解决的 MS Analytics 问题完全不同的问题，但也许我错了？
总而言之：
- 有没有人遇到过这个问题或类似的问题？你做了什么来解决它？
- 我正在构建的 Testflight 和/或 Mac 是否能够将不再在我的应用程序中的依赖项添加到发布版本中（就像它们被缓存在某个地方一样）？
- 如果没有人经历过这种情况，至少有人可以给我一些故障排除技巧吗？我的想法不多了。
先感谢您！
