Down is a fast Markdown/CommonMark rendering library for Swift, built on top of cmark. It parses Markdown into HTML or an AST and supports iOS, tvOS, macOS, and Linux.
Use cases
- render markdown to html in an ios app
- parse commonmark text in swift
- convert markdown to an ast
- display user-generated markdown content in a macos app
- render markdown strings in a tvos application
When to choose
- you need fast, spec-compliant CommonMark rendering in Swift
- you target Apple platforms or Linux with Swift Package Manager, CocoaPods, or Carthage
- you need both HTML output and AST access from Markdown
When to avoid
- you need a pure-Swift Markdown parser without a C dependency
- you need Markdown extensions beyond CommonMark (e.g., GFM tables)
- your project is not in the Swift ecosystem
