Project history and usage

SwiftPlantUML is a Swift CLI and Swift Package that generates PlantUML class diagrams from Swift source. It occupies a smaller but recognizable package-manager niche: source-code documentation tooling that can be installed with Homebrew or Mint and run from a project checkout.

Project history

The GitHub repository was created in January 2021. The official README describes a command-line tool and Swift Package for generating class diagrams powered by PlantUML from Swift files.

The project grew around SourceKit-backed Swift source inspection. Its README documents command-line operation, Swift Package use, an Xcode source editor extension, and configuration through `.swiftplantuml.yml`.

Adoption history

Official installation instructions include Homebrew, Mint, and source builds. The README also notes that the Homebrew installation previously used the maintainer's tap before the plain `brew install swiftplantuml` command became available.

GitHub release metadata shows public releases through the 0.8.x series in 2024. Compared with SwiftLint or SwiftFormat, the official record supports a narrower adoption story centered on diagram generation rather than general Swift build hygiene.

How it is used

Common usage is running `swiftplantuml` or the default `classdiagram` subcommand against files or directories containing Swift sources. The tool can emit or view generated PlantUML output and can use `.swiftplantuml.yml` for includes, excludes, access-level filtering, relationship display, and theming.

Because SwiftPlantUML hooks into SourceKit, the README tells users to run it with the same Swift toolchain used to compile the code.

Why package nerds care

SwiftPlantUML matters to package nerds as an example of a small Swift CLI that packages compiler-adjacent source inspection into a reusable tool. Its Homebrew and Mint support make architecture documentation reproducible without requiring every developer to build from source.

It also shows the packaging friction around SourceKit tools: the binary is simple to install, but correctness can still depend on the active Swift/Xcode toolchain.

Timeline
