Apple is building OpenAI and AI-powered Anthropic coding agents right into Xcode. New integrations in Xcode 26.3 will allow developers to use Anthropic’s Claude Agent and OpenAI’s Codex to write and edit code, update project settings, search documentation, and more.
Xcode is software that developers can use to build and test apps for iPhone, Mac, iPad, Apple Watch, and Apple TV. Both Claude and ChatGPT were previously available in Xcode, but this latest update will allow AI agents to perform actions inside the app, not just provide coding assistance.
Apple is also making Xcode available through the Model Context Protocol, an open-source standard that will allow developers to plug other AI tools into their app.
The news of Apple’s Xcode update comes just a day after OpenAI launched its AI-powered Codex app for Mac, which allows developers to co-write code with a team of AI agents. Apple says Xcode 26.3 will be available to Apple Developer Program members starting today, “with a release coming soon to the App Store.”
