Apple announces Xcode 26.3 with agentic AI integration

Despite some bumps in the road for its AI-driven features on the consumer side, Apple’s not slowing down on integrating the technology into its products. Today the company announced the latest update to its Xcode developer tool, which brings support for agentic AI coding.

Adding the agentic model opens up features like the ability for these AI models to get even deeper access to and more power with your projects. For example, the agents can look at and parse your project’s file structure to get more information, or even test and build the project all by itself. They’ll also have access to the latest documentation, allowing them to take advantage of the most recent APIs. Perhaps most impressively, these tools continue to iterate, repeatedly testing, verifying, and fixing errors until the project builds successfully.

This feature builds on top of the existing intelligence-powered tools and integrations that Apple introduced in Xcode 26 last year. Out of the box, Xcode 26.3 has built-in support for Claude Agent and ChatGPT’s Codex, allowing users to log in with their accounts or API tokens. But because this system is underpinned by Model Context Protocol (MCP), any other agent that supports the open standard can be integrated as well.

Xcode 26.3’s release candidate is available for download today.
