Mechanism
Breaks down how the skill works and what it produces, so you can quickly judge whether it fits your scenario and value.
When you need to test native code changes, custom modules, or Apple targets on physical devices or TestFlight, and Expo Go is insufficient. Also when creating custom dev clients for branch testing.
eas.json with a development profile (developmentClient: true).eas build locally or via cloud with --profile development; optionally --submit for TestFlight..ipa/.apk) via xcrun simctl, ideviceinstaller, or adb.npx expo start --dev-client.A distributable Expo development client for internal testing on devices/TestFlight, enabling native code testing outside Expo Go.
Use Cases
A team develops a custom native module not in Expo Go. They configure eas.json with a development profile, run `eas build -p ios --profile development --submit` to send a dev client to TestFlight, and testers install it to verify native behavior on devices. This avoids Expo Go limitations and speeds up QA for native features.
A developer on Linux without Xcode needs to test an iOS build on a local simulator. They run `eas build -p ios --profile development --local`, extract the .app, and use `xcrun simctl install booted` to install on a simulator. They connect via `npx expo start --dev-client` to iterate quickly on native changes without a Mac.
