lane :test do
  run_tests(
    scheme: "MortgageCalculator",
    code_coverage: true
  )
end

CI Integration:

- name: Run Tests
  run: xcodebuild test -scheme MortgageCalculator -enableCodeCoverage YES

4. App Store Submission

lane :validate_submission do
  sh("python3 ../app-store-submission/scripts/validate_submission.py .")
end

5. PDF Generation & Export

- name: Verify PDF Export
  run: |
    xcodebuild test \\
      -scheme MortgageCalculator \\
      -testPlan PDFExportTests

Complete Workflow Example

Initial Setup

1. Set up build configurations:

python scripts/setup_build_schemes.py com.mortgage.calculator .

2. Generate Fastlane config:

python scripts/generate_fastlane_config.py \\
  com.mortgage.calculator \\
  [email protected] \\
  ABC123DEF4 \\
  12345

3. Create CI/CD workflows:

python scripts/create_github_workflow.py all

4. Set up crash reporting:

python scripts/setup_crashlytics.py

One-Command Deployment

After setup, deployment becomes simple:

# Deploy to TestFlight
fastlane beta

# Release to App Store
fastlane release

# Run all quality checks
fastlane quality

# Test everything
fastlane test

Best Practices

1. Separate Configurations

Maintain distinct configurations for each environment with unique bundle IDs:

• com.example.app.debug (Debug)
• com.example.app.staging (Staging)
• com.example.app (Release)

This allows installing multiple builds simultaneously for testing.

2. Automate Code Signing

Use Fastlane Match to manage certificates and profiles in a git repository:

• One source of truth for all certificates
• Easy team onboarding
• No manual certificate management
• Works seamlessly in CI/CD

3. Quality Gates

Fail builds early on quality issues:

• Code quality audit must pass
• Architecture review must pass
• Tests must pass with 80%+ coverage
• App Store validation must pass

4. Incremental Build Numbers

Always increment build numbers automatically:

increment_build_number(
  build_number: latest_testflight_build_number + 1
)

5. Feature Flags for Rollouts

Use feature flags to:

• Gradually roll out new features
• A/B test implementations
• Kill switches for problematic features
• Environment-specific features

6. Monitor Crashes

Integrate Crashlytics from day one:

• Track errors in production
• Identify crash patterns
• Monitor user impact
• Fix issues proactively

7. Document Your Pipeline

Maintain a CI/CD documentation file:

• Required secrets
• Deployment process
• Rollback procedures
• Emergency contacts

Secrets Management

Required secrets for GitHub Actions:

# Code Signing
MATCH_PASSWORD              # Password for certificates repo
MATCH_GIT_BASIC_AUTHORIZATION  # Git access token

# Apple Developer
APPLE_ID                    # Apple ID email
APPLE_ID_PASSWORD          # Apple ID password
APP_SPECIFIC_PASSWORD      # App-specific password

# Notifications (optional)
SLACK_WEBHOOK              # Slack webhook URL

Set these in: Repository Settings → Secrets and variables → Actions

Troubleshooting

Build Failures

Issue: Code signing errors

# Reset Match certificates
fastlane match appstore --force

Issue: Tests failing in CI but passing locally

# Check simulator availability
xcrun simctl list devices

# Clean derived data
rm -rf ~/Library/Developer/Xcode/DerivedData

Issue: Wrong configuration being built

# Verify scheme configuration
xcodebuild -list -project MortgageCalculator.xcodeproj

Deployment Failures

Issue: TestFlight upload timeout

# Increase timeout in Fastfile
upload_to_testflight(
  skip_waiting_for_build_processing: true
)

Issue: App Store Connect authentication

# Verify credentials
fastlane spaceauth -u [email protected]

Quick Start Checklist

• Run create_github_workflow.py all for CI/CD
• Add required GitHub secrets
• Test locally with fastlane test
• Commit and push workflows
• Verify CI pipeline runs
• Deploy to TestFlight with fastlane beta
• Set up Crashlytics with setup_crashlytics.py
• Add feature flags with create_feature_flags.py

Real-World Example: Mortgage Calculator App

Before automation:

• ✗ Manual testing before each commit
• ✗ Remembering to run quality checks
• ✗ Time-consuming TestFlight uploads
• ✗ Manual App Store submissions
• ✗ Certificate management headaches

After automation:

• ✓ Push code → automatic quality validation
• ✓ Merge to main → automatic TestFlight deployment
• ✓ Tag release → automatic App Store submission
• ✓ Crashlytics tracks production issues
• ✓ Feature flags enable safe rollouts
• ✓ One command deploys everything: fastlane beta

Time savings: ~2 hours per week Quality improvement: 100% consistent quality checks Deployment confidence: Every release fully validated
