Apple Newsroom:

Xcode 26.3 introduces support for agentic coding, a new way in Xcode for developers to build apps using coding agents such as Anthropic’s Claude Agent and OpenAI’s Codex. With agentic coding, Xcode can work with greater autonomy toward a developer’s goals — from breaking down tasks to making decisions based on the project architecture and using built-in tools.

I don’t know if this is super-duper interesting news, but I think it’s super-duper interesting that Apple saw the need to release this now, not at WWDC in June.
