GitHub Copilot weekly release adds JetBrains Air and Xcode support

GitHub’s November 2 Copilot weekly release says Copilot is now available in JetBrains Air and in Xcode’s built-in coding assistant. The Xcode integration is in public preview and available starting with Xcode 27.3 beta. The update also lets users set up Agent Merge directly from pull requests, check reviewer status, request more reviews, quote comment text, and keep working when a chat hits its context limit. GitHub says it also streamlined session management, settings, and remote-task features in VS Code.
