QLSwift

A Quick Look plugin for macOS that renders Swift source files directly in the Finder preview pane. When a Swift file is selected, the plugin displays a syntax‑highlighted view of the code using Highlight.js, allowing developers to glance at content without opening an editor.

The tool is aimed at macOS users who work with Swift and want a fast visual overview of source files in the file system. It integrates with the native Quick Look infrastructure, so the preview appears alongside other file types and can be accessed via the space‑bar shortcut.

Installation is performed by copying the QLSwift.qlgenerator bundle into the user or system Quick Look directory and refreshing the cache with `qlmanage -r`. The plugin is released under the MIT license and is considered stable.
