FAQPage Schema
How do I configure EAS Build for iOS App Store deployment with Expo?▼

Configure EAS Build for Expo iOS deployment by installing the EAS CLI, logging in, and setting up eas.json and app.json to define build profiles before running the build and submit commands for App Store releases.

What's the best way to submit an Expo React Native app to TestFlight?▼

Submit an Expo React Native app to TestFlight by running an EAS Build for iOS with a production profile, then using the EAS CLI submit command to push the latest build directly to App Store Connect.

How do I manage iOS certificates and signing credentials for EAS Build?▼

Manage iOS certificates and signing credentials for EAS Build by letting the EAS CLI handle credential provisioning automatically, or by configuring custom certificate handling within your eas.json and environment variables.

Why does my Expo iOS build fail with signing errors during EAS submission?▼

Expo iOS build signing errors during EAS submission typically stem from mismatched App Store Connect integration, expired certificates, or incorrect environment variables configured in your eas.json and app.json files.

Do I need an Apple Developer account to deploy an Expo app to the App Store?▼

Yes, deploying an Expo app to the App Store requires an Apple Developer account for App Store Connect integration, which is necessary to generate the certificates and manage the TestFlight or production submission process.

Can I automate repeatable iOS deployments for Expo using EAS CLI?▼

Automate repeatable iOS deployments for Expo using EAS CLI by standardizing your eas.json build profiles and app.json configuration, ensuring consistent environment variables and credential handling across all build and submit workflows.
