How to Use EAS Build with Expo in React Native

To use eas build with Expo in React Native, first install the Expo CLI and configure your project with eas build:configure. Then run eas build --platform ios or eas build --platform android to start building your app in the cloud.

eas build:configure - Sets up your project for EAS Build by creating the necessary config files.
eas build --platform ios - Builds the iOS app in the cloud.

Not logging into Expo CLI with expo login before building.

Always check the build logs and follow Expo's documentation for setting up credentials.
