Swift Comments

New Course Coming Soon:

Get Really Good at Git

This tutorial belongs to the Swift series

A comment in Swift can take 2 forms: a single-line comment, and a multi-line comment.

A single-line comment is

//this is a comment

and it can be put at the end of a line of code:

let a = 1 //this is a comment

A multi-line comment is written using this syntax:

/* this
 is
    a multi-line
 comment
*/

Swift allows to nest multi-line comments:

/* this
 is
    a /* nested */ multi-line
 comment
*/

which is handy especially when commenting out large portions of code that already contains multi-line comments.

Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. A course that helps you feel less frustrated with Git. Launching Summer 2024. Join the waiting list!
