Unless.swift

Read Original

The article compares Ruby's 'unless' keyword with Swift's 'guard' statement, explaining that 'guard' enforces early returns and is not a direct equivalent. The author then presents a custom Swift implementation of 'unless' as a function, provides a GitHub link, and advises on integrating it into a project. It concludes with an invitation for feedback on syntax sugar for code readability.
