How do you implement automation of code integration and delivery in your project?

Automation of the integration and delivery process (CI/CD) in an iOS project is usually implemented using specialized tools and services, such as Jenkins, GitHub Actions, Bitrise, or Fastlane.

Main steps:

1. Automatic build trigger when code is pushed to the repository.
2. Running tests (unit tests, UI tests) to check quality.
3. Building the application with the required configurations.
4. Deployment to test devices or TestFlight for beta testing.

Example of using Fastlane for automating build and upload to TestFlight:

lane :beta do
  build_app(scheme: "MyApp")
  upload_to_testflight
end

This allows for faster release of new versions and reduces errors during manual operations.
