Xcode 27.3 adds GitHub Copilot to built-in coding assistant

Apple released Xcode 27.3 beta 1 with GitHub Copilot integration in its built-in coding assistant. Xcode previously supported ChatGPT, Claude (including Claude Agent with agentic coding capabilities), and Google Gemini. The addition means developers whose companies have standardized on GitHub Copilot can now use it directly within Xcode.

Key points

• GitHub Copilot is now available in Xcode's coding assistant starting with version 27.3 beta 1
• Xcode has been adding AI coding integrations since version 26, starting with ChatGPT and expanding to Claude, Codex (OpenAI), Claude Agent (Anthropic), and Google Gemini
• Agentic coding capabilities were introduced in Xcode 26.3, enabling AI assistants to help with tasks from writing boilerplate to updating entire projects based on documentation and file structure
• The beta includes Swift 6.4 and SDKs for iOS 27.3, iPadOS 27.3, tvOS 27.3, watchOS 27.3, macOS 27.3, and visionOS 27.3
• Expected stable release is in December 2026 alongside macOS 27.3

How to use it

• Download Xcode 27.3 beta 1 (requires macOS Tahoe 26.6 or later)
• Access GitHub Copilot through Xcode's coding assistant interface alongside other supported AI tools
• Use the coding assistant for tasks ranging from writing boilerplate code to project-level updates based on your codebase structure
• Developers with company GitHub Copilot licenses can now stay within their organization's approved tooling while using Xcode

Has anyone in the community tested GitHub Copilot in Xcode 27.3 beta yet? How does it compare to the existing Claude or Gemini integrations?
