Summary

Xcode 26.3 integrates AI agents from OpenAI and Anthropic.
AI can now build projects, run tests, and fix errors in Xcode.
Developers can use natural language to command AI coding assistants.

Apple has integrated advanced AI coding capabilities into its latest development suite with the release of Xcode 26.3. Developers can now utilize agentic tools, including those from Anthropic and OpenAI, directly within Apple's integrated development environment (IDE).

This significant update allows AI models to access more of Xcode's features, enabling them to perform complex automation tasks. The AI agents can explore projects, understand code structure, build applications, and execute tests to identify and resolve errors, referencing Apple's current developer documentation for best practices.

To facilitate this, Apple collaborated closely with AI providers, optimizing token usage and tool calling for efficient operation. Xcode employs the Model Context Protocol (MCP) to expose its functionalities, allowing compatibility with any MCP-compatible agent for tasks like project discovery and file management.
