在启用代码覆盖率时执行所有单元测试后，我们遇到了崩溃。请在下面找到堆栈跟踪

如果启用了代码覆盖，则此崩溃仅在 XCode 11.4 上发生。如果禁用代码覆盖率，它可以正常工作，但我们希望在执行单元测试后进行代码覆盖率。在 Xcode 11.3 中，单元测试在启用代码覆盖的情况下运行良好。任何人都可以让我们知道这个问题的解决方案。提前致谢。

编辑：分辨率

对我们来说，将其中一个依赖项的Macho-O-Type从可重定位对象文件更改为静态库解决了这个问题。但不确定这是否是导致此问题的唯一原因，因为可能有多种原因。

我有完全相同的问题，我仍然在受苦Xcode 11.4.1。我还看到你 @Arjuna 在 Apple 开发者论坛上发帖：

https://forums.developer.apple.com/thread/131988

到目前为止我没有找到任何解决方案，但我认为这与中引入的功能有关Xcode 11.4

https://developer.apple.com/documentation/xcode_release_notes/xcode_11_4_release_notes

继Releases Notes我们有：

When building a scheme that has been converted to use test plans and whose active test plan has code coverage enabled, Xcode now includes code coverage instrumentation when building for the ‘Run’ action, in addition to the ‘Test’ action. This matches the behavior of building schemes which don’t use test plans and have code coverage enabled, and avoids unnecessary rebuilds when alternating between running and testing actions.

我很确定这与此有关，但我仍然无法找到解决它的方法。
