How can you write a comment in Swift?

by

In Swift programming language, single-line comments are started with double slashes (//).

For example:

// This is a single line comment.
Multi-line comment: Multiline comments are started with a forward-slash followed by an asterisk (/*) and end with an asterisk followed by a forward-slash (*/).

For example:

/* this is multi
Line comment*/

To write a comment in Swift, you can use either of the following methods:

  1. Single-line comment:
// This is a single-line comment
  1. Multi-line comment:
/*
This is a multi-line comment.
It can span multiple lines.
*/

Both single-line and multi-line comments are used to annotate your code with explanations, reminders, or any information you want to convey to yourself or other developers working on the project. They are ignored by the compiler and have no effect on the execution of the code.
