我有一个奇怪的问题，我经常在构建和运行时遇到此错误
clang: error: unable to execute command: Killed: 9
clang: error: linker command failed due to signal (use -v to see invocation)
其他时候，我收到一条说明could not attach to simulator或类似内容的对话框消息。
我不确定何时开始，我已尝试清理并删除派生数据。
失败的实际命令：

通过以下方式清理Xcode派生数据：
rm -rf ~/Library/Developer/Xcode/DerivedData/*
答案 1 :(得分：0)
我不确定我是如何让它工作的，但我发现哪个文件经常无法链接，罪魁祸首是SomeClass.o。我尝试移动swift文件的内容，但这没有用，所以我最终重构了这个类的名称，这就行了。
在我看来，某个地方有一个缓存，当删除派生数据时没有被删除，我希望这有助于其他人，因为这个bug是个婊子
