Choosing 'bare' requires manual native setup.

Using 'classic' or 'custom' are not valid init options.

Fix the error in the EAS Build configuration file to specify the build profile.

React Native

{
  "build": {
    "production": {
      "releaseChannel": "default",
      "distribution": "store",
      "android": {
        "buildType": "[1]"

💡 Hint

Common Mistakes

Using 'apk' builds a single APK, not the recommended bundle.

Using 'debug' is for development, not production release.

The app-bundle build type creates an Android App Bundle (.aab) recommended for Play Store uploads.

Fill both blanks to configure EAS Build to use a specific Apple team and enable auto-provisioning.

React Native

{
  "ios": {
    "teamId": "[1]",
    "autoProvisioning": "[2]"
  }
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Leaving teamId blank or incorrect causes build failures.

Setting autoProvisioning to 'disabled' requires manual setup.

Replace YOUR_TEAM_ID with your Apple Developer Team ID and set autoProvisioning to enabled to let EAS manage certificates automatically.

5fill in blank

Fill all three blanks to create an EAS Build profile that targets iOS, uses the release channel 'prod', and uploads the build to the app store.

React Native

{
  "build": {
    "[1]": {
      "releaseChannel": "[2]",
      "distribution": "[3]"
    }
  }
}

Drag options to blanks, or click blank then click option'

Aios

Bprod

Cstore

Dandroid

Attempts:

💡 Hint

Common Mistakes

Using 'android' instead of 'ios' for iOS builds.

Using 'store' is required to upload to the app store.

This profile builds for iOS, uses the 'prod' release channel, and uploads the build to the App Store.
