Testing Apple Xcode 27 Coding Agent: TestFlight Success but Complex Game Development Fails
atShruti · x · 2026-08-01
A dev team tested the new Apple Xcode 27 beta coding agents by attempting to build a multiplayer poker app.
Initial Success
- The agent successfully deployed the app to TestFlight, autonomously opening a browser and creating identities on Apple's developer portal.
Core Limitations
- Building the game on Apple GameKit failed due to the lack of groups, shared standings, and shared game state.
- The author noted that GameKit is built for arcade matches, not for persistent group play among friends.
- Conclusion: Swift and GameKit currently do not feel "agent ready."
Final Pivot
- The team ultimately rebuilt the app using Expo, React Native, and Firebase, running 3 agents to assist.
