Fastlane

iOS Fastfile

# ios/fastlane/Fastfile
default_platform(:ios)

platform :ios do
  desc "Run tests"
  lane :test do
    run_tests(scheme: "MyApp")
  end

  desc "Build and upload to TestFlight"
  lane :beta do
    increment_build_number(xcodeproj: "MyApp.xcodeproj")
    match(type: "appstore", readonly: true)
    build_app(scheme: "MyApp", export_method: "app-store")
    upload_to_testflight(skip_waiting_for_build_processing: true)
    slack(message: "New iOS beta uploaded to TestFlight")
  end

  desc "Deploy to App Store"
  lane :release do
    match(type: "appstore", readonly: true)
    build_app(scheme: "MyApp", export_method: "app-store")
    upload_to_app_store(
      submit_for_review: true,
      automatic_release: false,
      force: true
    )
  end
end

Android Fastfile

# android/fastlane/Fastfile
default_platform(:android)

platform :android do
  desc "Run tests"
  lane :test do
    gradle(task: "test")
  end

  desc "Build and upload to Play Store internal track"
  lane :beta do
    gradle(task: "bundleRelease")
    upload_to_play_store(
      track: "internal",
      aab: "app/build/outputs/bundle/release/app-release.aab"
    )
  end

  desc "Promote to production"
  lane :release do
    upload_to_play_store(
      track: "internal",
      track_promote_to: "production",
      rollout: "0.1" # 10% rollout
    )
  end
end

Code Signing

iOS (match)

# Matchfile
git_url("https://github.com/org/certificates.git")
storage_mode("git")
type("appstore")
app_identifier("com.example.myapp")

# Usage
match(type: "development")  # Dev certificates
match(type: "appstore")     # Distribution certificates

Android (Keystore)

# Generate keystore (once)
keytool -genkey -v -keystore release.keystore \
  -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000

# Store securely - NEVER commit to git
# Use CI secrets or encrypted storage
