DevOps for Swift (iOS/macOS) Developers

This book is the first practical guide of its kind, bridging the gap between classic iOS/macOS development and modern DevOps practices. The author, with many years of experience building large-scale Swift applications and managing infrastructure, shows how to turn a chaotic build and delivery process into a predictable, fast, and reliable pipeline.

What this book is about

The book covers the full lifecycle of a Swift application — from the first commit to publication on the App Store and Mac App Store. You will learn how to set up continuous integration and delivery (CI/CD), automate routine operations with Fastlane, organize testing on real devices in the cloud, and implement monitoring and logging in a production environment.

• Git strategies and working with Xcode Cloud — effective branching models for teams using Git and Xcode Cloud.
• Fastlane from A to Z — writing your own lanes, working with Match for certificate management, automating screenshots, and beta distribution via TestFlight.
• Docker and Swift on the server — containerizing Vapor and Kitura projects, orchestration with Docker Compose, deployment to VPS and cloud platforms.
• Continuous testing — integrating XCTest/XCUITest into the CI pipeline, parallel test execution, using GitHub Actions and Bitrise.
• Monitoring and logging — setting up Crashlytics, Sentry, Datadog for Swift applications, alerting, and performance analysis.
• Deployment automation — publishing to App Store Connect, version management, creating release notes, A/B testing with Feature Flags.
• Security and secrets — working with .env, key encryption, using Vault and Swift Package Manager for dependency management.

Who this book is for

The book is intended for Swift developers with at least 1 year of experience who want to master DevOps tools and automate the processes of building, testing, and delivering applications. It will be useful for both solo developers and members of large teams. Knowledge of basic Swift syntax and experience with Xcode are required, but no special knowledge of DevOps is needed — all concepts are explained from scratch.

What you will learn

• How to reduce the time between a commit and a release from 2 days to 2 hours.
• How to eliminate "build errors on my machine" using containerization and a unified CI environment.
• How to automatically generate and sign builds for different environments (dev, staging, production).
• How to set up crash report monitoring and receive notifications about performance degradation.
• How to securely manage certificates and provisioning profiles within a team.

At the end of each chapter, you will find practical exercises and checklists to help you immediately apply the knowledge gained in a real project.

Additional materials: The book contains links to a repository with ready-made Fastlane configuration files, Dockerfiles, CI/CD templates for GitHub Actions and Bitrise, as well as example scripts for automating routine tasks.

If you want to stop spending hours on manual builds and start delivering high-quality applications quickly and without errors — this book is for you.
