When to Use

• Use when this upstream workflow matches the user's stated goal.
• Use when the task requires the procedures documented in this skill.

App Store Deployment

EAS service - costs apply. Cloud builds use EAS plan resources, and EAS services have free-tier and paid-plan limits. Apple Developer and Google Play memberships are separate. Check https://expo.dev/pricing for the requested service.

This skill covers building and releasing iOS and Android apps with EAS: Expo and other React Native projects, plus existing native apps. EAS is a delivery service; native apps can use it without adding Expo or React Native to their runtime. The native setup walkthrough currently covers SwiftUI/UIKit on iOS.

Choose the project path

• SwiftUI/UIKit app with no React Native runtime: read [references/native-ios.md] before changing its build configuration. Keep the Xcode project and Swift code as the app's source of truth. The Expo/React Native quick-start and development-client examples below do not apply to this path.
• Native Android app with no React Native runtime: preserve its existing native build setup. See [references/play-store.md] for submission; the Swift/iOS setup instructions do not apply. A dedicated native Android setup walkthrough is not yet included.
• Expo/React Native app: use the quick-start below, then the relevant store reference.
• Adding React Native screens to an existing native app: use expo-brownfield for that integration; return here for distribution.

Use the archive and icon checks in [references/native-ios.md] during initial native iOS setup, after changing versioning, bundle IDs, or icons, or when diagnosing a rejected upload. Routine releases follow the EAS build/submit flow and the processing and availability checks in [references/testflight.md]. A successful EAS build or a queued submission does not establish Apple acceptance, tester access, or an App Store release.

Expo / React Native Quick Start

Install EAS CLI

npm install -g eas-cli
eas login

Initialize EAS

npx eas-cli@latest init

eas init links or creates the EAS project. Run eas build:configure to create build profiles in eas.json; preserve existing project and store identifiers when a release setup already exists.

Build Commands

Production Builds

# iOS App Store build
npx eas-cli@latest build -p ios --profile production

# Android Play Store build
npx eas-cli@latest build -p android --profile production

# Both platforms
npx eas-cli@latest build --profile production

Submit to Stores

# iOS: Build and submit to App Store Connect
npx eas-cli@latest build -p ios --profile production --auto-submit

# Android: Build and submit to Play Store
npx eas-cli@latest build -p android --profile production --auto-submit

# Expo / React Native shortcut for iOS TestFlight
npx testflight

Web & API Route Hosting

Deploying an Expo website or Expo Router API routes to EAS Hosting (npx expo export -p web then eas deploy) is covered by the eas-hosting skill. This skill focuses on native app store releases.

EAS Configuration

Example for an Expo / React Native project (native Swift profiles are in references/native-ios.md):

{
  "cli": {
    "version": ">= 16.0.1",
    "appVersionSource": "remote"
  },
  "build": {
    "production": {
      "autoIncrement": true,
      "ios": {
        "resourceClass": "m-medium"
      }
    },
    "development": {
      "developmentClient": true,
      "distribution": "internal"
    }
  },
  "submit": {
    "production": {
      "ios": {
        "appleId": "your@email.com",
        "ascAppId": "1234567890"
      },
      "android": {
        "serviceAccountKeyPath": "./google-service-account.json",
        "track": "internal"
      }
    }
  }
}
