IOS Build Issues

Common Errors in IPA Generation (iOS Build Issues)

1. Command PhaseScriptExecution failed with a nonzero exit code

   Possible Solutions :

   1. Run the following command to clean the build :

      cd ios
      xcodebuild clean

   2. If you're using CocoaPods, try :

      cd ios
      pod install --repo-update

   3. Restart Xcode and rebuild the app.

2. Command CompileSwift failed Possible Solutions :

   1. Upgrade your Swift version :

      sudo xcode-select --switch /Applications/Xcode.app

   2. Ensure Build System is set to "New Build System" in Xcode.

3. The linked framework 'React-Core' is missing Possible Solutions :

   • Run :

   cd ios
   pod install

4. CocoaPods version mismatch Possible Solutions :

   1. Update CocoaPods :

      sudo gem install cocoapods
      pod install --repo-update

   2. The APK will be located at :

    android/app/build/outputs/apk/release/app-release.apk

5. Unable to upload IPA to TestFlight/App Store Possible Solutions :

   • Upload using Transporter (Mac App Store) or run :

   xcrun altool --upload-app -f app.ipa -t ios --apiKey YOUR_KEY --apiIssuer YOUR_ISSUER_ID

6. Unable to upload IPA to TestFlight/App Store Possible Solutions :

   1. Ensure you have excluded arm64 for simulators in Xcode → Build Settings :

   2. Excluded Architectures → arm64 (for Debug builds)

   3. Remove arm64 exclusion for Release builds.

General Fix for iOS Build Issues

cd android

pod install --repo-update
cd ..
npx react-native run-ios

Note: Make sure that you do not use the ^ (caret) symbol while installing this package. Using ^ allows npm to automatically install a newer version, which can again lead to version mismatch problems.
