Testing Xcode 27 Coding Agent: Handles Deployment but Fails Complex Game Logic
atShruti · x · 2026-08-01
A dev team tested the Apple Xcode 27 beta coding agents by attempting to build a multiplayer poker app.
- Initial Success: The agent successfully deployed the app to TestFlight from Claude designs on its own, even opening a browser to create identities on Apple's developer portal.
- Core Failure: Building the game on GameKit failed due to the lack of persistent groups, shared standings, and shared game state. Swift and GameKit simply don’t feel 'agent ready'.
- Final Solution: The team pivoted away from native development, rebuilding the app using Expo, React Native, and Firebase, designed in pen dot dev with 3 agents running in parallel.
