SwiftLint enforces Swift style conventions with 19.5K stars - the de facto standard linter that integrates seamlessly into Xcode and catches style violations before your team does

Every Swift team has that one developer who nitpicks code style in PRs. SwiftLint automates those conversations by enforcing consistent Swift conventions across your entire codebase. Built by Realm and trusted by thousands of iOS teams, it catches everything from inconsistent spacing to complex architectural violations before they hit your repo.

What sets SwiftLint apart is its deep integration with Swift’s own SwiftSyntax parser, giving it native understanding of your code rather than regex-based guessing. It highlights violations directly in Xcode, supports custom rules, auto-fixes common issues, and integrates with every major CI system. With over 200 built-in rules covering everything from naming conventions to performance patterns, it enforces the same style guidelines used by major Swift projects.

Whether you’re a solo developer wanting consistent habits or leading a team tired of style bikeshedding, SwiftLint installs in minutes via Swift Package Manager, Homebrew, or CocoaPods. The 19.5K stars and active community mean you’re adopting a proven standard, not experimenting with someone’s weekend project.
