我有一个非常奇怪的崩溃，仅在发布版本(App Store + TestFlight)和 Apple Watch Series 3 上发生 。 如果我在我的系列 3 上调试时运行它，它工作正常。在较新的 watch (系列 4+)上，App Store 和调试版本运行良好。
我的 watch 应用使用 SwiftUI。有人知道这里发生了什么吗？这是 SwiftUI 错误还是我做错了什么？
这是我从系列 3 中得到的崩溃日志(符号):

在调试了一天之后，我找到了一个解决方法，即使我不明白到底发生了什么......
阅读后this (RxSwift 中的类似问题)，我尝试禁用 Dead Code Strippingbuild设置，然后从 TestFlight 安装工作!据我所知，这看起来像是一个 Swift 链接器错误，它是从我的 32 位设备上的代码中以某种方式触发的(感谢 lorem ipsum 提供此提示!)。
关于SwiftUI Apple Watch 应用程序在发布版本时崩溃(仅限系列 3)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/64335093/
