## What it is
SwiftLint is a tool that enforces Swift style and conventions based on community-accepted style guide rules. It is built on SwiftSyntax with some rules using Clang and SourceKit, and integrates with Xcode and Swift Package Manager.

## Use cases
- enforce swift style guide rules in a project
- lint swift code in ci
- check swift code style automatically
- integrate linting into xcode builds
- keep swift codebase consistent across a team

## When to choose
- you write Swift and want automated style enforcement
- you want CI-integrated linting for Swift projects
- you need Xcode or SPM plugin integration

## When to avoid
- your project is not written in Swift
- you need a general-purpose multi-language linter

## Facets
- artifact type: cli-tool
- maturity: stable
- function: linter, code-review, cli, developer-tools
- domain: developer-tools, programming-languages
