Unity developers know the pain of manual iOS, macOS, and visionOS builds—provisioning profiles, signing certificates, and Xcode configuration eat up valuable time. This guide explains how to automate the entire pipeline using GitHub Actions and Buildalon. The process starts with an Apple Developer Account and a working Unity project, then connects services for registration, authentication, and distribution to testers.

The core workflow requires registering your app in App Store Connect and generating an App Store Connect API Key to bypass two-factor authentication hurdles. Buildalon's `unity-xcode-builder` action simplifies the complex Xcode build and signing steps. You'll configure a macOS runner, set unique build numbers, and choose between sideloading an installable `.ipa` file for rapid testing or uploading directly to TestFlight for broader beta distribution.

For sideloading, the build artifact can be installed on registered devices via Finder. For team testing, the workflow uploads to TestFlight and automatically invites your specified group. This automation transforms a time-consuming manual process into a repeatable CI/CD pipeline, accelerating iteration cycles for Unity projects targeting Apple's ecosystem.
