A recent talk at FOSDEM 2026 showcased ElementaryUI, a new open-source framework bringing Swift to the browser. The project aims to provide a safer and more expressive alternative to JavaScript for web frontend development. It leverages WebAssembly and Embedded Swift, making it a viable option for building web applications using Swift's strengths.

ElementaryUI allows developers to create state-driven user interfaces using a SwiftUI-inspired syntax. The talk covered setting up a development environment, composing views, handling user inputs, and implementing animations. A live-coding session demonstrated the framework's features, including hot-reloading. This approach offers rapid iteration, which is crucial for front-end development today.

The project's goal is to enable Swift developers to branch out into web development seamlessly. It also provides web enthusiasts with an alternative to JavaScript. The speaker, Simon, a developer based in Austria, is actively involved in the project. The talk offers a practical entry point for those interested in making Swift in the browser a reality, which is a growing trend.

WebAssembly is maturing and opening new possibilities for cross-platform development. We can expect to see more frameworks and tools emerge that embrace Swift for web development. The ultimate goal is to provide a unified experience across various platforms. This will lead to increased code reuse and improved efficiency for developers.
