如何在所有抛出上设置断点? [英] How to set a breakpoint on all throws?

问题描述

有什么方法可以指定一个断点以停止所有"throw"语句? (符号断点)

Is there any way how we can specify a breakpoint to stop on all 'throw' statements? (symbolic breakpoint)

guard let id = UInt(idString),
      let changeset = UInt(changesetString),
      let uid = UInt(uidString)
else {
      throw OSMVectorMapDescriptionError.ElementAttributeConversionError(element: xmlNode, attributeº: nil)
}

推荐答案

刚刚在Xcode 8.3中找到了一个替代方案:菜单中有一个"Swift Error Breakpoint"选项，用于添加新的临时断点:

Just found an alternative in Xcode 8.3: there is a "Swift Error Breakpoint" option in the menu for adding new ad-hoc breakpoints:

如果右键单击新创建的断点，甚至可以指定要打破的特定Error符合类型.

If you right-click the newly created breakpoint, you can even specify a particular Error-conforming type to break on.
