Apple launches Xcode 26.3, brings even more AI power to coding on Mac

• Xcode 26.3 RC now has agentic AI support – full release coming soon
• Anthropic Claude Agent and OpenAI Codex are fully integrated
• Xcode's capabilities are also being made available via MCP

Apple has announced a major upgrade as part of Xcode 26.3 which brings more powerful AI coding to the platform, including agentic AI to automate some of the tasks needing less human oversight.

The IDE, which was built by Apple specifically for developing apps for Apple products, now supports Anthropic's Claude Agent and OpenAI's Codex directly within the interface.

Xcode already had some limited ChatGPT and Claude integration, but version 26.3 deepens this by giving the agents access to more of Xcode's tools natively.
