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.

OpenAI has launched a new macOS app for its Codex platform, introducing a desktop interface designed to help users manage multiple AI agents at once.
