# Xcode Playgrounds

Open a Swift `.playground` package in Marked. Marked reads `contents.swift` (and related pages in multi-page playgrounds) and separates Markdown comments from executable Swift.

- Markdown commentary renders with your chosen style.
- Executable Swift is shown inside syntax-highlighted fenced code blocks suitable for reading or printing.

This is ideal for literate programming snippets, teaching examples, or documenting playground-based experiments without exporting to a separate Markdown file first.
