The mobile development platform has introduced a new verification system that lets automated coding assistants run and record changes in a cloud environment before submitting them to developers. Called Expo Simulators, the tool allows an AI agent to start a cloud iOS simulator, install an application and perform interactions, then generate screen recordings and screenshots as proof of the change.
Expo developed the tools to address a bottleneck in agentic coding where AI assistants produce mobile code faster than human teams can manually review it. The system integrates these visual checks into the AI loop, permitting human reviewers to access and test the specific build via a shared link before final approval.
