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：编译命令因信号而失败（使用 -v 来 见调用）

但我无法找出导致分段错误的 swift 文件。

Answer 1

尝试禁用 Swift Compiler Optimization for Release 更具体地说：在您的目标中 > 构建设置 > 优化级别 > 发布 > 无优化

Answer 2

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。

我不知道为什么但解决了。

感谢 Sohil R. Memon 抽出宝贵时间。

Answer 3

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：

swift::Lowering::TypeConverter::getFunctionInterfaceTypeWithCaptures(swift::CanTypeWrapper, swift::AnyFunctionRef) + 242 5 快速

如果您仍然无法调试问题，请将演示代码或上述文件放到网上，我会帮助您。
