Continuous Integration (CI) is an essential process for automating workflows in software development, particularly for iOS apps, by using tools like fastlane and Buildkite Pipelines. This process minimizes manual steps, such as code linting and testing, which can slow down development. Fastlane facilitates the creation of complex workflows, called lanes, to handle various tasks needed for iOS projects, such as linting with SwiftLint, testing with scan, and output formatting with xcbeautify. Buildkite Pipelines supports running these CI processes on different infrastructures, allowing developers to maintain control over access to their code and credentials. Utilizing CI templates from Buildkite can quickly establish a pipeline, but customization is often necessary to align with specific project requirements. Running a CI pipeline efficiently identifies and resolves issues in code changes, as demonstrated in setting up and troubleshooting a sample iOS app pipeline. Embracing CI enables developers to focus more on coding while the CI system handles routine testing and validation.
