DTCoreText: Open Source HTML and Rich Text Rendering Engine for Apple Platforms
A legendary open-source framework authored by Oliver Drobnik, providing high-performance parsing and rendering of HTML and rich text attributes into native iOS and macOS UI components, powering thousands of production applications.
CoreText parsing library; handles standard HTML tags and CSS styles while omitting complex JavaScript DOM manipulation.
Context: Objective-C and Swift native runtime on iOS, iPadOS, and macOS.
View missionSwiftMCP: Native Model Context Protocol Framework for Apple Platforms
Open-source implementation of the Model Context Protocol (MCP) in pure Swift, enabling macOS and iOS applications to securely host and connect tools to LLMs with strict memory-safety and sandboxing.
Platform-bound to Swift 6 and Darwin environments; streaming large payloads requires custom backpressure handlers.
Context: Swift 6, Model Context Protocol (MCP), Unix domain sockets, and Anthropic API.
