SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Expo Go cannot run custom native code, third-party native modules, config plugins, or Apple targets like widgets and app clips. This Skill guides you through creating custom development clients so you can test native code changes on physical devices. ## Core Features & Use Cases - EAS Configuration: Set up a development build profile in eas.json with developmentClient, autoIncrement, and remote app version source. - Cloud and Local Builds: Build iOS and Android dev clients via EAS Build in the cloud or locally with Xcode and Android toolchains. - TestFlight Distribution: Build and submit an iOS dev client to TestFlight in one command for internal testing. - Use Case: You added a native module that Expo Go does not bundle. Use this Skill to configure a development profile, run eas build -p ios --profile development --submit, install the build from TestFlight, and connect it to your local Metro bundler. ## Quick Start Use the expo-dev-client skill to configure a development EAS profile and build an iOS development client for my app.

Frequently Asked Questions about expo-dev-client

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build an Expo development client?▼

Run eas build with a development profile that sets developmentClient to true in eas.json. Use eas build -p ios --profile development for iOS or -p android for Android, and add --local to build on your own machine.

When do I need a development client instead of Expo Go?▼

You need a development client when using local Expo modules, third-party native modules not bundled in Expo Go, config plugins, Apple targets like widgets or app clips, or when testing remote push notifications and universal links.

How do I submit an Expo dev client to TestFlight?▼

Run eas build -p ios --profile development --submit to build the dev client in the cloud and automatically submit it to App Store Connect. You receive an email when the build is ready in TestFlight, then install it on your device.

Does building an Expo dev client cost money?▼

The expo-dev-client package is open source and local builds are free. Cloud builds via EAS Build consume your EAS plan's build minutes, and iOS device or TestFlight distribution requires a paid Apple Developer account.

Why does my EAS build fail with signing errors?▼

Signing errors usually come from missing or invalid iOS credentials. Run eas credentials to configure certificates and provisioning profiles, or use --clear-cache to clear the build cache and retry.
