Copilot lands in Xcode and JetBrains Air, plus Agent Merge in its app

GitHub’s weekly Copilot roundup for November 2 brings Copilot to JetBrains Air and to Xcode’s built-in coding assistant, and adds Agent Merge, which lets Copilot merge a pull request once it is ready.

Merging, settings and sessions across four surfaces

The GitHub Copilot app gets the most changes. Agent Merge can be set up directly from a pull request, and GitHub says it now stays enabled while required checks or rules are still pending. The app also shows reviewer status, lets users request more reviews, and lets them select comment text to quote it or discuss it with Copilot.

When a conversation hits its context limit, users can compact it or inspect what fills the space from the error itself. Dropping files on “New” in the sidebar starts a session, and CSV and TSV files open as tables with sticky headers and a source view. Session management also gets lighter: pinned sessions whose pull requests have merged or closed can be archived, several sessions can be pinned or unpinned at once, and nested chats can be separated without losing the conversation. My Work now supports more than ten saved custom views. Users can also write personal instructions on which tool requests Copilot may approve without asking. Those instructions are opt-in and apply to local sessions.

In Copilot CLI, /settings now opens one dashboard for plugins, MCP servers and more, with search across all settings.

VS Code 1.145 adds experimental chat view modes that collapse or expand reasoning and tool calls. Remote browser previews and interactive canvases arrive in the Agents window as a preview. Local automations support cron expressions and custom agents from the workspace. Files can be added to chat from outside the workspace through Add Context > Files, though cloud sessions accept only images. Past terminal output now renders as it is expanded rather than all at once.

Two IDE integrations with very different footing

In JetBrains Air, users can track several agent sessions and run tasks locally in their JetBrains IDE or in the cloud through Air Teams, on their existing Copilot subscription. In Xcode, Copilot works inside the native assistant as a public preview, starting with Xcode 27.3 beta.

Our earlier coverage fills in the conditions. According to our report on the Air integration, cloud runs need a JetBrains account in an Air Teams-enabled business organization, plus a Copilot subscription that the Air administrator has enabled. Cloud tasks draw on the user’s Copilot plan, not JetBrains AI credits. The Air plugin is labeled alpha on the JetBrains Marketplace.

For Xcode, our earlier piece reports that GitHub says all Copilot plans are supported, and that the setup requires macOS Tahoe 26.6 or later, with Copilot configured under Xcode > Settings > Intelligence. The older Copilot for Xcode extension stays available.

Copilot follows the agents into other people’s tools

The analysis here is about track record. Xcode 26.3 added agentic coding with Anthropic’s Claude Agent and OpenAI’s Codex in February 2026, and Air launched in public preview in March 2026 with Codex, Claude Agent, Gemini CLI and JetBrains’ Junie, according to coverage cited in our earlier reports. Copilot is therefore arriving second, in environments where rival agents already sit, rather than defining them.

That fits a pattern in GitHub’s own releases. The same day, we covered a dashboard change that counts chat and VS Code agent usage. Taken together, GitHub is widening where Copilot runs while building the measurement for it.

The Air governance gap is worth noting. Our earlier report says Air’s analytics and governance do not cover Copilot usage, and admins can disable Copilot but not set Copilot spending limits there. Agent Merge, with its opt-in approval instructions, raises a similar question for the Copilot app: how much autonomy teams will grant, and how they will audit it.

What the changelog leaves unsaid

The changelog gives no dates for general availability of either IDE integration, and no pricing or premium-request details. It does not say which models are available in Xcode or Air, or how Agent Merge decides a pull request is ready beyond mentioning required checks and rules. GitHub’s descriptions are its own, and no independent testing is cited. The Xcode preview depends on a beta toolchain, so it is a poor fit for production machines.

Developers can use the Copilot app, CLI and VS Code 1.145 changes now. Anyone wanting Xcode needs the 27.3 beta, and cloud tasks in Air need an Air Teams organization.
