TestFlight 安装的应用程序因 Swift 程序包管理器依赖项而崩溃
TestFlight installed app crash with Swift Package Manager dependencies
我们已经迁移了一些 CocoaPod 依赖项，以便在 Xcode11 中构建并与 Swift 包管理器链接。但是，每当我们将应用程序提交到 AppStore Connect 并使用 TestFlight 分发时，应用程序当它尝试使用 SPM 链接依赖项之一的 API 时崩溃。其他构建（临时和开发）工作正常。一些 SPM 依赖项也链接了 2 个应用程序扩展。
有没有人遇到过这个问题，你知道这是什么问题吗and/or如何解决？
正在附加崩溃的堆栈跟踪。这发生在 ObjectMapper 依赖项中。

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

首先，是SPM的编译问题。只需回滚到 CocoaPods。
直到 Xcode 11.2.1，苹果还没有修复这个问题。
删除所有派生文件，清理项目。然后使用 release 配置尝试 运行 您的项目。现在您应该能够重现崩溃了。
我在一个 iOS 项目中使用了两个名为 Moya 和 Parchment 的库，以及从 CocoaPods 迁移而来的 Swift 包管理器。当执行引用这两个库的逻辑时，从 TestFlight 下载的应用程序崩溃。
而且崩溃日志看起来完全是胡说八道，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.
