Apple has just released Xcode 26.3, and it's a big step forward in terms of the company's support of coding agents. The new release expands on the AI features the company introduced with Xcode 26 at WWDC 2025 to give systems like Claude and ChatGPT more robust access to its in-house IDE.

The improved AI agent access in Xcode has made vibe coding astoundingly simple for beginners, to a level where some apps can be made without manually writing any code at all.
