Getting started with iOS CI and fastlane

Continuous Integration (CI) is an automated process that helps developers maintain high code quality and catch bugs early in the development cycle. By automating linting, testing, and other manual processes, CI tools like fastlane and Buildkite Pipelines can significantly speed up app development. This blog demonstrates how to create and run automated CI pipelines with fastlane for iOS apps, using SwiftLint for code style enforcement, scan for test automation, and xcbeautify for displaying Xcode test output. The process involves setting up a Fastfile to define workflows (lanes) and customizing Buildkite's CI templates to fit the project requirements. By adopting CI, developers can focus on writing code while their infrastructure runs tests automatically, catching issues early and ensuring consistent code quality.
