Apple is building OpenAI and Anthropic’s AI-powered coding agents directly into Xcode. New integrations in Xcode 26.3 will give developers the ability to call upon Anthropic’s Claude Agent and OpenAI’s Codex to write and edit code, update project settings, search documentation, and more.
Xcode is the software developers can use to create and test apps for the iPhone, Mac, iPad, Apple Watch, and Apple TV. Both Claude and ChatGPT were previously available inside Xcode, but this latest update will allow AI agents to take action inside the app, rather than just provide coding assistance.
Apple is also making Xcode available through the Model Context Protocol, an open-source standard that will enable developers to plug other AI tools into the app.
The news of Apple’s Xcode update comes just one day after OpenAI launched its AI-powered Codex app on Mac, which lets developers write code alongside a team of AI agents. Apple says Xcode 26.3 will be available to members of the Apple Developer Program starting today, “with a release coming soon on the App Store.”
