在运行swiftlint版本0.24.0时，会报告错误。运行autocorrect表示文件已更正。然而，swiftlint的后续运行没有进行任何修改。
请参阅尝试lint并更正两个文件Player.swift和Prize.swift。
MacBook-Pro-5: Developer$ swiftlint

这是另一次运行，但这次只有一个文件Prize.swift只包含一个可纠正的违规行为。同样，autocorrect不会修改：
MacBook-Pro-5:P Developer$ swiftlint

请注意，.swiftlint.yml文件的存在与否与此无关。
缩写 - 即仅显示相关规则 - 来自swiftlint rules的输出如下所示。请注意，在三次违规行为中，colon肯定是可以纠正的。

有关swiftlint autocorrect如何成功运行的任何想法？可能会有一些我遗漏的明显配置或参数？我咨询了https://github.com/realm/SwiftLint，但没有用。
答案 0 :(得分：2)
并非所有SwiftLint规则都可以更正，这意味着它们将在您运行swiftlint autocorrect后保留。如果您运行swiftlint rules，您可以看到一个表格 - 除其他外 - 显示哪些规则可以更正。
我不确定您使用的是什么版本的SwiftLint，但我不认为line_length或operator_whitespace是可纠正的。你必须自己处理这些问题。
