How do I Upload a .ipa file to App Store Connect?

This worked for me:


xcrun altool --validate-app --file "$IPA_PATH" --username "$APP_STORE_USERNAME" --password @keychain:"Application Loader: $APP_STORE_USERNAME"

xcrun altool --upload-app --file "$IPA_PATH" --username "$APP_STORE_USERNAME" --password @keychain:"Application Loader: $APP_STORE_USERNAME"
