This walkthrough shows how to configure GitHub Copilot CLI as an ACP agent in Xcode by specifying the binary path and passing the --acp flag as an argument. Once set up, GitHub Copilot appears alongside built-in agents (Claude, OpenAI, Gemini) and can perform tasks like building the app, reading project files, and planning features. Some limitations exist around slash commands, MCP server visibility, and model switching within ACP mode, but the model can be changed via the CLI before starting a new conversation. ## Full article daily.dev links to this article rather than hosting it.
