GitHub Copilot Agent Mode provides AI-powered assistance that can understand and modify your codebase directly. With Agent Mode, you can:

- Get intelligent code edits applied directly to your files

- Run terminal commands and view their output without leaving the interface

- Search through your codebase to find relevant files and code snippets

- Create new files and directories as needed for your project

- Get assistance with enhanced context awareness across multiple files and folders

- Run Model Context Protocol (MCP) tools you configured to extend the capabilities

Agent Mode integrates with Xcode's environment, creating a seamless development experience where Copilot can help implement features, fix bugs, and refactor code with comprehensive understanding of your project.

You can receive auto-complete type suggestions from GitHub Copilot either by starting to write the code you want to use, or by writing a natural language comment describing what you want the code to do.
