SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Configuring xcodebuild for macOS app distribution is complex and error-prone, with common failures including signing mismatches, incorrect destination syntax, failed notarization, and broken CI/CD pipelines that block app releases.

Core Features & Use Cases

  • End-to-End Distribution Workflows: Covers building, archiving, exporting, notarizing, and stapling for native macOS, Mac Catalyst, and universal binary apps across Developer ID, Mac App Store, and development distribution channels.
  • CI/CD Pipeline Templates: Includes production-ready GitHub Actions and Makefile examples for automated release pipelines, test matrices, and secure notarization credential management.
  • Troubleshooting & Validation: Provides a review checklist and targeted fixes for common xcodebuild failures, signing errors, notarization issues, and architecture mismatches. Use case example: A macOS developer can use this skill to configure a CI pipeline that builds a universal binary, signs it with a Developer ID certificate, submits it for notarization, and staples the ticket automatically on every tagged release.

Quick Start

Use the xcode-macos-toolchain skill to configure a GitHub Actions workflow that automatically builds, notarizes, and staples a release-ready macOS app for direct distribution outside the Mac App Store.

Frequently Asked Questions about xcode-macos-toolchain

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate macOS app notarization and stapling in a CI/CD pipeline?▼

Automate macOS app notarization and stapling in a CI/CD pipeline by configuring xcodebuild to build and archive the app, then submitting it to Apple via notarytool using securely managed credentials before automatically stapling the ticket. This skill provides production-ready GitHub Actions templates to fully automate this release workflow.

What is the correct xcodebuild destination syntax for building Mac Catalyst apps?▼

The correct xcodebuild destination syntax for building Mac Catalyst apps requires specifying the proper platform variant within your build command to avoid destination mismatches. This skill provides the exact destination configurations needed for native AppKit, SwiftUI, and Mac Catalyst variants to ensure reliable builds.

Why does xcodebuild fail with code signing mismatches when exporting a macOS app archive?▼

xcodebuild fails with code signing mismatches during macOS app archive export due to incorrect provisioning profiles or missing hardened runtime enablement settings. This skill provides targeted troubleshooting steps and validation checklists to resolve signing errors, configure Developer ID certificates, and satisfy notarization requirements.

How do I build a universal binary for macOS app distribution outside the Mac App Store?▼

Build a universal binary for macOS app distribution by configuring xcodebuild to compile for both Apple Silicon and Intel architectures, signing the combined executable with a Developer ID certificate, and submitting it for notarization. This skill covers the complete workflow for creating and distributing universal binaries.

Does this macOS toolchain support GitHub Actions for automated release pipelines?▼

Yes, this macOS toolchain supports GitHub Actions by providing production-ready pipeline templates for automated release workflows, test matrices, and secure notarization credential management. You can automatically build, sign, notarize, and staple tagged releases directly within your CI environment.
