Apple just quietly shipped "JARVIS" inside Xcode 26.3

Hey everyone, huge news for the developers here.

Apple just released Xcode 26.3, and they have natively integrated the Claude Agent SDK. This isn't just another auto-complete update, it is full agentic coding.

The three massive changes that matter:

Visual Verification: Claude can actually "see" your UI previews. It looks at the pixels and fixes layout bugs automatically.
Full Context: It reads your whole project architecture, not just the file you have open.
Autonomy: You give it a high-level goal, and it edits files, builds the project, and fixes errors on its own until it works.

The "human in the loop" role just moved from writing code to reviewing architecture.

Let me know if you are planning to test this out!
