OpenAI announced yesterday Codex Desktop, a new native macOS app that treats AI coding agents like teammates you can direct, review and set loose on long tasks.

In a newsroom post, Apple announced the new agentic capabilities within Xcode. The new feature is part of the Xcode 26.3 update, which was rolled out to developers via the company's developer portal.
