MCP Night 4 demo recap: Expo's Evan Bacon puts the iOS simulator in the browser
Blog post from WorkOS
At MCP Night 4, Evan Bacon, head of AI at Expo, presented a novel approach to mobile app development by integrating the iOS simulator with browser-based environments, specifically using npx serve-sim to run the simulator inside a browser. This method capitalizes on the strengths of coding agents that are more adept at web development due to advanced browser tooling and verification loops, which are often lacking in mobile app development. The in-browser simulator allows for real-time interaction and inspection, bridging the gap between web and mobile development by providing features like console log integration, element inspection, and even camera functionality through generative video or webcam use. This approach not only simplifies the development process of mobile apps but also enhances the agent's ability to interact with the app in a manner similar to web platforms, suggesting a shift in focus from protocol mastery to leveraging existing web-based verification loops for mobile app creation.
