About SwiftPlantUML
SwiftPlantUML generates PlantUML class diagrams from Swift code. It adds a source editor command in Xcode that diagrams the current file or the selected code, and a Finder action for one or more Swift files. A companion app holds the diagram options and the extension switches. It suits Swift developers who want a quick class diagram. The README recommends its command-line tool for diagrams across a whole project.
The README does not state a macOS version. Install it with Homebrew (brew install swiftplantumlapp) or by copying the app from the releases page, then enable the extensions under System Settings > Extensions. The README warns that the Xcode extension can take about 30 seconds to start on first launch. The last commit is from January 2024.
