A WKWebView-based Markdown renderer for iOS with syntax highlighting, dark mode, and SwiftUI support.
MarkdownView is a native iOS library that renders Markdown content as styled HTML within a `UIView` or `SwiftUI` view. It solves the problem of displaying formatted text, code snippets with syntax highlighting, and mathematical expressions in iOS apps without requiring complex custom text rendering logic. It leverages markdown-it for parsing and highlight.js for code styling, providing a robust and extensible solution.
iOS developers building apps that need to display formatted documentation, readme content, code examples, or any Markdown-based text within a native interface. It's particularly useful for educational apps, developer tools, or content-heavy applications.
Developers choose MarkdownView for its seamless integration with both UIKit and SwiftUI, out-of-the-box features like syntax highlighting and dark mode, and the flexibility to customize styling and extend functionality via plugins. It eliminates the overhead of building a custom Markdown renderer from scratch.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Leverages markdown-it, a well-established library, ensuring accurate parsing and extensibility through plugins, as highlighted in the README.
Uses highlight.js out of the box to provide language-specific coloring for code blocks without additional setup, a key feature mentioned.
Supports system appearance changes via prefers-color-scheme CSS, reducing manual styling effort for adaptive interfaces.
Allows custom CSS injection and plugin support (e.g., KaTeX for math), enabling advanced styling and functionality extensions.
Requires iOS 16.0 or later, excluding older devices and limiting compatibility for apps with broader audience needs.
Relies on WKWebView for rendering, which can introduce higher memory usage and slower load times compared to native solutions.
Adding plugins requires embedding JavaScript strings, a cumbersome process for iOS developers unfamiliar with web technologies, as noted in the plugin examples.
