Create Comments In Swift

Swift is a versatile and intuitive language developed by Apple for iOS, iPadOS, macOS, watchOS, and tvOS application development. Learning Swift allows you to develop apps using modern features and safe programming patterns, in this guide, we will explore how to create comments in Swift.

Code snippet for Creating Comments in Swift

Here’s a simple Swift code snippet that illustrates the approach:

// This is a single line comment

/* This is a multi-line comment
  which spans multiple lines
*/

/// This is a single line documentation comment

/**
 This is a multi-line
 documentation comment
*/

Code Explanation for Creating Comments in Swift

Swift supports different types of comments, making it easier for developers to note down important information within the code. Let’s take a look at these types one by one:

1. Single-line comment: Swift uses two forward slashes // to denote a single-line comment. Anything from the // to the end of the line is considered a comment and not executed as code.

// This is a single-line comment

2. Multi-line comment: Swift uses /* to start a multi-line comment and */ to end it. Everything within these symbols is considered a comment. Multi-line comments can span multiple lines, helping when you want to write longer notes or temporarily disable a section of code.

/* This is a multi-line comment
which spans multiple lines
*/

3. Single-line documentation comment: Swift uses three forward slashes /// to indicate a single-line documentation comment. These comments are often used to generate documentation for your code and can be exported using a documentation generator tool.

/// This is a single line documentation comment

4. Multi-line documentation comment: Similar to above, Swift uses /** and */ to denote the start and end of a multi-line documentation comment respectively. This can be used when your documentation requires more explanation and spans multiple lines.

/**
This is a multi-line
documentation comment
*/

The use of comments in your Swift code can significantly enhance its readability and maintainability, helping both you and others understand your code better.
