🏗️ Start Coding

If you'd like to set up the project locally, see our development guide. For this app:

1. Copy dotenv.sample.txt to .env
2. Run npm i to install dependencies

Release build

1. Hardcode stage to prod EnvironmentHelper.ts
2. Increment the version number in app.config.js, package.json, android/app/build.gradle and ios/B1Mobile/Info.plist
3. Run npm run build:android to generate a Google Play release
4. Run npm run build:ios to generate an iOS release

iOS Versioning and Submission

To avoid App Store rejections after the Expo eject, keep the native project in sync before each iOS release.

1. Update expo.version and expo.ios.buildNumber in app.config.js (and bump package.json if needed).
2. Mirror those values into the native project:
   • Set CFBundleShortVersionString and CFBundleVersion in ios/B1Mobile/Info.plist.
   • Update MARKETING_VERSION and CURRENT_PROJECT_VERSION in ios/B1Mobile.xcodeproj/project.pbxproj.
3. Commit the changes so the release history is tracked.
4. Run eas build --platform ios --profile production and wait for the build to finish.
5. Submit with eas submit --platform ios --profile production (or use the Expo dashboard).
6. If App Store Connect reports a duplicate version/build, repeat the steps with higher numbers and rebuild.
