Comments in Swift are non-executable text that can be used to explain or document your code. They are ignored by the compiler, so they do not affect the execution of your program.
There are two types of comments in Swift: single-line comments and multiline comments.
- Single-line comments begin with two forward slashes (//).
- Multiline comments begin with a forward slash and asterisk (/*) and end with an asterisk and forward slash (*/).
Here is an example of a single-line comment:
// This is a single-line comment.
Here is an example of a multiline comment:
/*
This is a multiline comment.
It can span multiple lines.
*/
Comments can be used to explain what your code is doing, why you wrote it that way, or to provide other helpful information. They can also be used to temporarily disable code that you are not currently using.
It is a good practice to use comments in your code to make it more readable and understandable. Comments can help other developers understand your code, and they can also help you remember what your code is doing when you come back to it later.
Here are some tips for writing good comments:
- Keep your comments brief and to the point.
- Use clear and concise language.
- Avoid jargon and technical terms.
- Use comments to explain the purpose of your code, not to repeat the code itself.
- Update your comments when you make changes to your code.
Comments are an important part of good programming practice. By using comments, you can make your code more readable, understandable, and maintainable.
