Building Your Own DSL with @resultBuilder in Swift: HTML Builder

This tutorial series aims to transform messy HTML string concatenation into beautiful, type-safe Swift code using a complete HTML DSL. By the end of the tutorial, you'll be able to build a production-ready HTML DSL that can be used in real-world projects. The DSL will provide automatic XSS protection, type-safe markup, and comprehensive test suites. The core architecture of the DSL is based on a solid foundation of protocols and structs, including an HTMLElement protocol and an Element struct. The @resultBuilder attribute is used to enable the beautiful syntax of the DSL. The DSL provides complete element support for all HTML needs, smart conditional rendering, and automatic security through HTML escaping. Testing is also an essential part of the DSL, with robust testing strategies to ensure reliability. The benefits of using the DSL include reduced bugs, better readability, easier maintenance, type safety, security, and performance. The complete tutorial covers foundation architecture, complete @resultBuilder implementation, full HTML element library, production testing strategies, and real-world usage examples. The next part of the series will cover advanced patterns, performance optimization, and production deployment strategies.
