Apple just pushed Xcode one step further: the editor now natively supports the Claude Agent SDK from Anthropic. What does that mean for you as a developer or app creator? In short, more autonomy inside the IDE for complex programming and visual verification tasks — without leaving Xcode.

What changes in Xcode with Claude Agent SDK

Until recently, Xcode included access to Claude Sonnet 4 to help with code snippets, debugging and documentation on a request-by-request basis. That was useful, but limited to turn-by-turn interactions.

With Xcode 26.3 the integration is native with the Claude Agent SDK, the same engine that powers Claude Code. Now Claude can run longer, more complex workflows directly in the IDE: subagents, background tasks and plugins are available without making you leave Xcode.

What Claude can do inside Xcode

• Visual verification with Previews

  Claude can capture Xcode Previews and see how the interface you're building actually renders. Can you imagine handing the AI a SwiftUI view and having it detect and fix visual issues by itself? That's exactly the goal: iterate closer to the expected design from the first attempt.
