Comments

Comments

Comments allow you to document your code. Comments are ignored by the Swift compiler, and are only useful for people reading your code base.

Single-line comments begin with two forward-slashes //.

Example:

    // Hello, single-line comment!

Multiline comments begin with a forward-slash followed by an asterisk /* and ends with an asterisk followed by a forward-slash */

Example:

   /* Hello,
   multiline-line comment! */
