During GitHub Universe 2024, GitHub announced that GitHub Copilot code completion in Xcode is available in public preview. The project is open source at CopilotForXcode

GitHub Copilot has been available as VS Code extension for a while, but this is first time we have official extension for Xcode.

GitHub Copilot for Xcode supports multiple programming languages commonly used in the Apple ecosystem, including Swift and Objective-C

Here's how to use this new extension in Xcode. I'm using Xcode 16 on macOS Sequoia. You can download latest Xcode from xcodereleases
