在 Objective-C 中，我们可以使用 __LINE__ 和 __PRETTY_FUNCTION__ 宏.这些在 Swift 语言中没有公开.有没有其他方法可以在 Swift 中获取类似信息?

In Objective-C, we could use the __LINE__ and __PRETTY_FUNCTION__ macros. These are not exposed in the Swift language. Is there another way to get similar information in Swift?

推荐答案

Swift 语言参考定义 一些提供这种行为的特殊文字":

The Swift Language Reference defines a few "special literals" that offer this behavior:

Literal        Type     Value

#file          String   The name of the file in which it appears.
#line          Int      The line number on which it appears.
#column        Int      The column number in which it begins.
#function      String   The name of the declaration in which it appears.
