Production Releases
Production uses the production profile (store signing) and eas submit.
Firebase is not involved here at all.
iOS → App Store Connect
eas build --profile production --platform ios --local --output ./build/app-production.ipa
eas submit --profile production --platform ios --path ./build/app-production.ipa
From App Store Connect you then send the build to TestFlight or to review.
eas submitonly uploads the binary — it does not submit it anywhere on its own.
Android → Google Play
eas build --profile production --platform android --local --output ./build/app-production.aab
eas submit --profile production --platform android --path ./build/app-production.aab
eas submit for Android needs a Google Play service-account key. If it isn’t
configured yet, EAS walks you through creating one.
Submit metadata (Apple ID, App Store app id, bundle id) lives in the
submit.production block of eas.json, so you don’t pass it on the command line.
Once eas submit finishes, the build is uploaded but not live — it’s sitting
in TestFlight (iOS) or a Play track (Android). See
Store Submission for the console steps that take it to
production.
With EAS cloud build credits you can build without --local and then submit
the most recent cloud build with --latest (no --path needed):
eas submit --profile production --platform ios --latest.
