Swash combines the raw speed of AppKit's native text engine with the rich, fluid layouts of SwiftUI.

• ⚡ Blazing-Fast Native Engine – Powered by an optimized NSTextView wrapper (SwashTextView) for instant rendering, smooth typing, and robust scroll performance.
• 🔍 Native Quick Look Extension – Built-in macOS Quick Look preview plugin so you can preview Markdown files instantly in Finder or via spacebar preview using the exact same rich rendering logic as the Swash split view preview pane.
• 🫧 Floating Selection Bubble Menu with Code Dropdown – Select text to trigger an elegant, contextual bubble overlay allowing you to style your prose instantly. When code formatting is active, an integrated dropdown selector lets you choose between multiple formats and programming languages (Inline, Plain Block, JavaScript, Swift, Python, HTML, CSS, JSON, Bash) with dynamic menu positioning.
• 📑 macOS Document-Based Architecture – Full native integration with the macOS system. Benefit from automatic saving, file history, sandboxed security, and standard system menus.
• 🎨 Premium Styled Markdown & Code Blocks – Implements a sophisticated, custom-crafted MarkdownParser to beautifully render headings, lists, bold/italic, and links. Features gorgeous block-level and inline code formatting, automatically hiding markup delimiters (``` and languages) and displaying code cleanly inside styled containers with subtle background highlight overlays. Spellchecking and grammar corrections are automatically disabled inside code blocks to keep your code pristine and free of red squiggly underlines.
• 🛠️ Full macOS Integration – Leverages system-level spellchecking, autocorrect options, undo/redo handling, and native keyboard navigation.

Every detail of Swash has been fine-tuned to create a calm, delightful, and highly-productive writing environment:

• Perfect Line Spacing & Padding: Customized text container insets provide standard 20px padding margins to keep text perfectly centered and comfortable to read.
• System Color Adaptive: Automatically respects Light & Dark mode settings, shifting colors with beautiful macOS vibrancy.
• Floating Component Synchronization: The floating selection menu is synchronized dynamically with bounds modifications and viewport scroll offsets, staying exactly where you expect it.

• A Mac running macOS 15.0+
• Xcode 16.0+ or Swift Command Line Tools

Swash features a modern, automated release pipeline powered by GitHub Actions. Every push to the main branch automatically:

1. Imports Apple Code Signing Certificates securely from GitHub Secrets (if configured) or falls back gracefully to ad-hoc signatures.
2. Compiles and Code Signs the native .app bundle, .zip archive, and .dmg disk image binaries targeting Apple Silicon and Intel Macs.
3. Packages the app into:
   • A signed, installer-ready .dmg Disk Image
   • A signed .zip Archive
4. Generates a changelog detailing all commits and contributions since the previous release.
5. Publishes a GitHub Release with the assets attached and ready to download instantly!
