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。然而，每当我们将应用程序提交到AppStore Connect并使用TestFlight进行分发时，应用程序在尝试从SPM链接的依赖项之一使用API时就会崩溃。其他构建(adhoc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。
有人遇到过这个问题吗？你知道问题是什么和/或如何解决吗？
正在附加崩溃的堆栈跟踪。这种情况发生在ObjectMapper依赖关系中。

2019-11-27更新
在相关的Swift bug帖子中，有人找到了一个变通方法：
在我们的应用程序目标中设置DEAD_CODE_STRIPPING=NO可以修复崩溃。
原始帖子
首先，这是SPM的编译问题。只需回滚到CocoaPods即可。
直到Xcode 11.2.1，苹果还没有解决这个问题。
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。
我在一个iOS项目中使用了两个名为Moya和Parchment的库，Swift Package Manager是从CocoaPods迁移过来的。从TestFlight下载的应用程序在执行引用这两个库的逻辑时崩溃。
崩溃日志看起来完全是胡说八道，指出了方法描述符的内存对齐问题。
苹果在Xcode发布说明中提到了一个已知的问题，我不知道它是否相关：
如果iOS、tvOS或watchOS应用程序使用构建动态库的Swift Package，则无法将其提交到应用商店。(55564324(
解决方法：修改包清单以构建静态库。
