如何识别导致分段错误的源文件：11

Question

尝试在Xcode 8.3.3上编译Swift 3.1时遇到问题 Xcode说：

  

：0：错误：无法执行命令：分段错误：11   ：0：错误：编译命令因信号失败（使用-v to   见调用）

但我无法找出导致分段错误的swift文件。

Answer 1

Segmentation fault: 11的原因是您在.swift文件中编写的复杂表达式或函数。您可以通过检查错误中提到的行号来调试问题，例如：

  

迅速降低:: ::的TypeConverter :: getFunctionInterfaceTypeWithCaptures（SWIFT :: CanTypeWrapper，   swift :: AnyFunctionRef）+ 242 5 swift

如果您仍无法调试此问题，请将演示代码或上述文件放在网上，我会帮助您。

Answer 2

尝试为发布禁用Swift编译器优化 更具体：在目标>构建设置>优化级别>发布>无优化中

Answer 3

无法从错误日志中识别分段错误swift文件。

我尝试删除源代码中的一些swift文件并重新导入它们然后现在分段错误错误现在消失了。

我不知道为什么会解决。

感谢Sohil R. Memon的时间。
