Apple has added GitHub's Copilot to the coding assistant built into Xcode, with the first beta of Xcode 27.3, released on the evening of 3 November 2026 in the US. The release notes file it under Coding Intelligence as a one-line entry.
“GitHub Copilot is now available in the coding assistant.”
Tim Cook, then Apple CEO, in a statement · 9to5mac.com ↗
Copilot joins the agents Xcode already supports: Claude, Codex and Google's Gemini, which MacG describes as Antigravity while 9to5Mac says Gemini has been there since Xcode 27. Setup is light, and the release is a beta, so details may still move. Xcode downloads a small package, then sends the developer to GitHub's site to sign in. Copilot offers only an Auto setting, so the plan and the task decide which model answers. A free tier works, but with tight limits and lighter, older models such as Claude Haiku 4.5 or GPT-5 mini.

The beta carries more than Copilot. It ships Swift 6.4 and the 27.3 SDKs for iOS, iPadOS, tvOS, watchOS, macOS and visionOS, and needs a Mac on macOS Tahoe 26.6 or later. Device Hub now accepts a dropped .app or .ipa to install, a link to open or a file to save, and option-drag stands in for two-finger touch gestures, with input support for older simulators (iOS before 18, tvOS before 18, watchOS before 11 and visionOS before 2). The RenderPreview MCP tool gains interactive delayed snapshots for macOS previews. The built-in MCP server also lets models generate macOS app previews, with bug fixes for agents. Developers can also test Siri AI integration in their apps, and MacRumors notes new APIs for the coming touchscreen MacBook Pro. On-device debugging covers iOS 17 and later, tvOS 17 and later, watchOS 10 and later, and visionOS.
About Xcode
Xcode is Apple's developer suite and the integrated development environment of the same name for the Mac, used to build software for macOS, iOS, iPadOS, watchOS, tvOS and visionOS. It first appeared in late 2003 and is free on the Mac App Store and Apple's developer site.
Its AI features arrived in steps. Apple announced Swift Assist, a cloud-based coding companion, at WWDC 2024 but never shipped it. WWDC25 replaced it with a built-in ChatGPT integration and a way to plug in other model providers, in Xcode 26. Xcode 26.3, on 26 February 2026, added agentic coding and exposed its agent interface over MCP. Xcode 27, announced on 10 June 2026, added a native Google Gemini integration alongside Claude Code and OpenAI's Codex.
9to5Mac calls the addition good news for developers at companies that standardised on Copilot. MacG welcomes it too, but says Xcode keeps trailing the pace of AI releases: it still ships GPT-5.6 variants while OpenAI is at 6.1. The route here began with ChatGPT in Xcode 26, followed by Claude. Xcode 26.3 in February 2026, which opened agentic coding with Anthropic's Claude Agent and OpenAI's Codex, and Xcode 27 then brought Gemini, a redesigned interface, interactive planning and multi-turn chats. The final Xcode 27.3 is expected in December.
