/** First line text.
 Putting \\n doesn't create a new line.\n One way to create a newline is by making sure nothing is on that line. Not even a single space character!
 @a Italic text @em with @@a or @@em.
 @b Bold text with @@b.
 @p Typewritter font @c with @@p or @@c.
 Backslashes and must be escaped: C:\\foo.
 And so do @@ signs: user@@example.com
 Some more text.
 @brief brief text
 @attention attention text

Swift 文档注释是差不多可以按照 markdown 格式走的,输入 /// 或者 /** */ 就可以了。也支持类似 Note、Attention 这样的关键字。
/// text
///
/// - Attention: attentionText
