Xcode Previews

Xcode's live visual rendering system that shows real-time previews of SwiftUI views as developers write code.

Xcode Previews is Apple's built-in feature that renders SwiftUI views in real time within the IDE, allowing developers to see visual output of their UI code without building and running the full application. In Xcode 26.3's Claude integration, the agent can capture these previews programmatically to verify its own UI work, creating a closed-loop system where the AI writes code, checks the visual result, and iterates autonomously.
