INLOOPX QLPlayground

QLPlayground is a Quick Look generator that renders Xcode Playgrounds directly in macOS Finder previews. It works with both single‑page and multi‑page playground files, displaying the source code with syntax highlighting provided by the SyntaxHighlighter library. The preview is generated by a .qlgenerator bundle that can be installed system‑wide or per user, and it can be refreshed with the standard qlmanage command.

The tool is aimed at developers who use Xcode Playgrounds and want a quick visual overview without opening the playground in Xcode. By placing the QL generator in the appropriate QuickLook directory, users can see highlighted playground content in file browsers, facilitating faster navigation and sharing of code snippets.

Installation can be performed by building the project or downloading a pre‑built release, and a Homebrew‑Cask formula is also available. Customization of the rendered output is possible by editing resource files inside the generator bundle. The software is released under an MIT‑style license, allowing free use, modification, and distribution.
