iOS App Publishing with CI/CD

3 posts · Mar 2019 – Jun 2023

What this trail covers

GitLab CI/CD integrates with fastlane to automate the building, signing, and distribution of iOS applications to TestFlight. This includes configuring build environments, managing code signing using fastlane Match with GitLab Secure Files, and integrating with App Store Connect API for uploading builds. The process leverages macOS shared runners and defines CI jobs for building and releasing beta versions. This post details the process for Android code signing using Project-level Secure Files and CI variables.

All GitLab trails
  1. Tutorial: iOS CI/CD with GitLabThis post details the integration of GitLab CI/CD with fastlane for iOS app publishing. It covers installing fastlane, initializing fastlane Match with GitLab Secure Files for code signing, generating project access tokens, updating Xcode configurations, integrating with App Store Connect API for build uploads, and provides sample Fastfile and .gitlab-ci.yml configurations. The CI jobs are set up to run on macOS shared runners, with a beta job manually triggered.
  2. Mobile DevOps with GitLab, Part 2 - Code signing for Android with GitLabThis post details the process of generating an Android Keystore file using `keytool`, configuring `build.gradle` to use the keystore for release signing, and setting up GitLab CI/CD to automate the signing process. It covers uploading the keystore as a Secure File and configuring CI variables for `ANDROID_KEY_ALIAS`, `ANDROID_KEYSTORE_PASSWORD`, and `ANDROID_KEY_STOREFILE`. The `.gitlab-ci.yml` example demonstrates downloading secure files using `glab` and executing the Android build.
  3. How to publish iOS apps to the App Store with GitLab and fastlaneThis post introduces a new capability for automating iOS app publishing to TestFlight using GitLab CI/CD and fastlane. It outlines the prerequisites for Apple App Store configuration, the setup of a macOS runner with the shell executor, and the configuration of fastlane components (Appfile, Fastfile, Gymfile). The .gitlab-ci.yml file is provided to demonstrate the pipeline, including bundle installation, fastlane execution, and artifact collection. It also details necessary environment variables for authentication and code signing.
