ios - TestFlight 安装的应用程序崩溃与 Swift 包管理器依赖项

Question

我们已经迁移了一些 CocoaPod 依赖项，以便在 Xcode 11 中构建并与 Swift Package Manager 链接。但是，每当我们将应用程序提交到 AppStore Connect 并使用 TestFlight 分发时，应用程序在尝试使用来自 SPM 之一的 API 时崩溃链接的依赖项。其他构建(即席和开发)运行良好。一些 SPM 依赖项还链接了 2 个应用程序扩展。

有没有人遇到过这个问题，你知道问题是什么和/或如何解决吗？

附加崩溃的堆栈跟踪。这发生在 ObjectMapper 依赖项中。

在 related Swift bug post 中，有人找到了解决方法:

Setting DEAD_CODE_STRIPPING = NO in our app’s target fixes the crash.

首先是，是SPM的编译问题。只需回滚到 CocoaPods。

在 Xcode 11.2.1 之前，Apple 还没有修复这个问题。

删除所有派生文件，清理项目。然后尝试使用 release 配置运行您的项目。现在您应该能够重现崩溃。

我在 iOS 项目中使用了两个名为 Moya 和 Parchment 的库，带有从 CocoaPods 迁移的 Swift Package Manager。当执行引用两个库的逻辑时，从 TestFlight 下载的应用程序崩溃。

而且崩溃日志看起来完全像废话，指向一个方法的方法描述符的内存对齐问题。

Apple 在 Xcode 发行说明中提到了一个已知问题，不知道是否相关:

If an iOS, tvOS, or watchOS app uses a Swift Package that builds a dynamic library, it cannot be submitted to the App Store. (55564324)

Workaround: Modify the Package manifest to build a static library.
