EAS Mobile Deployment

How It Works

BUILD and SUBMIT are independent EAS services. A build creates the binary. A submit uploads an existing binary to a store. They never need to run together.

• eas build creates an IPA (iOS) or AAB (Android) and stores it on EAS
• eas submit takes an existing build artifact and uploads it to App Store Connect or Google Play
• A single build can be submitted multiple times (e.g. first to internal track, then to production)
• A failed submission does not require a rebuild

Distribution Settings (CRITICAL)

The distribution field controls build type, but does NOT automatically upload to stores:

Important: distribution: "store" alone does NOT upload to stores. You must explicitly submit builds using a separate eas submit command after the build completes.

CI/CD Pattern: Split build and submit into separate jobs:

1. Build job: eas build --platform ios --profile production --non-interactive
2. Submit job: eas submit --platform ios --profile production --latest --non-interactive

This allows builds to succeed even if submission fails, and enables retrying submissions without rebuilding.

Version Management

Two separate version concepts:

This is controlled by two eas.json fields:

• appVersionSource: "remote" -- EAS stores build numbers on its servers, not in local files. Required for CI/CD where builds happen on different machines/branches.
• autoIncrement: true (on the build profile) -- EAS bumps the build number on every build. You never touch it.

This means you can build 10 times for version 1.2.0 -- each gets a unique build number (1, 2, 3...) and the stores accept all of them. You only bump version in app.json when you want a new user-facing release.

For apps already in stores, sync the current store build number to EAS first:

eas build:version:set

Submit Profiles

Submit profiles in eas.json control where a build goes:

Android track options: internal, alpha, beta, production. Android releaseStatus options: draft, completed, inProgress, halted.

Note: Use "draft" for new apps. Builds upload successfully but require manual publish in Google Play Console. Once your app is published and you want automatic rollouts, you can change to "completed".

iOS submit requires ascAppId -- your App Store Connect App ID (numeric, found in the ASC URL for your app). When submitted, builds appear in TestFlight after ~10-15 min of Apple processing.

Note: Submit profiles are used with eas submit --profile NAME, not with eas build. The profile name passed to eas submit determines the destination (e.g., --profile internal submits to Android internal track).

CI/CD Workflow Pattern

The recommended pattern splits build and submit into separate jobs:

build-ios:
  steps:
    - run: eas build --platform ios --profile production --non-interactive

submit-ios:
  needs: build-ios
  steps:
    - run: eas submit --platform ios --profile production --latest --non-interactive

Benefits:

• Builds can succeed even if submission fails
• Retry submissions without rebuilding
• Clearer separation of concerns
• Better error isolation

For Android: Use --profile internal for submit to send to internal testing track, or --profile production for production track.

For iOS: Use --profile production for submit to send to TestFlight (appears after ~10-15 min Apple processing).

Credentials

Only EXPO_TOKEN needs to be a GitHub secret. All store credentials (Apple ASC API key, Google Play service account JSON) are managed by EAS and configured once locally via:

eas credentials

EAS stores them encrypted and uses them during cloud builds/submissions.

Gotchas

iOS build succeeds but not in TestFlight -- Build succeeded but submit step didn't run or failed. The IPA is built but not uploaded. Fix: Run eas submit --platform ios --profile production --latest --non-interactive to submit the existing build.

"Build number already exists" -- Missing appVersionSource: "remote" + autoIncrement: true, or stale local version. Fix with eas build:version:set.

Android "track not found" -- The track must exist in Google Play Console first. Create it and upload one build manually before CI submissions work.

iOS not in TestFlight after upload -- Apple processing takes 10-15 min. Check App Store Connect status.

--latest picks wrong build -- It always picks the most recent successful build. Use --id for precision, or check with eas build:list --platform ios.

First Android submission ever -- Google requires the very first AAB to be uploaded manually via Play Console. After that, EAS Submit works.

Profile name confusion -- --profile production in eas build refers to the BUILD PROFILE NAME, not the release destination. It means "production-quality build" (optimized, release config). The distribution: "store" creates store-ready binaries. After building, you submit with eas submit --profile production which uses the SUBMIT PROFILE. iOS goes to TestFlight first, then you manually promote to App Store when ready.
