A command-line tool for linting, rendering, and generating Swift Playground books from YAML or markdown.
Playgroundbook is a command-line toolset for working with Swift Playground books, Apple's interactive learning format for Swift. It provides utilities to lint existing books for correctness, render new books from YAML configuration files, and generate playgrounds directly from markdown documentation with embedded Swift code. It solves the problem of manually assembling and validating Playground books, which can be error-prone and time-consuming.
iOS educators, tutorial authors, and developers creating interactive Swift learning materials for Swift Playgrounds or Xcode. It's particularly useful for those producing structured, multi-chapter educational content.
Developers choose Playgroundbook because it automates the complex packaging process of Playground books, ensures compliance with Apple's format, and allows content to be authored in familiar formats like markdown, reducing manual effort and potential errors.

Renders complete .playgroundbook files from a YAML config, handling chapters, pages, and resources automatically—saving manual effort in assembling Apple's complex format.
Lints existing .playgroundbook files against Apple's specifications, catching errors early to ensure compliance and avoid distribution issues.
Converts markdown with Swift code blocks into runnable Xcode playgrounds, preserving referenced images and enabling content-first authoring in familiar formats.
Supports glossary:// links for interactive term definitions and automates asset copying, enhancing educational content without manual file wrangling.
Admits it 'only scratches the surface' of Apple's Playground Book format, missing advanced options like custom live view configurations or rich media integrations.
Requires strict YAML formatting (no tabs, spaces only) and has non-intuitive constraints like lexicographical page ordering and no periods in page names, leading to setup errors.
Demands specific markdown syntax (triple backticks with no space for Swift code) and limits non-code blocks, reducing flexibility for mixed-content tutorials.
