Apple's Xcode Now Supports the Claude Agent SDK

• Xcode 26.3 ships native Claude Agent SDK integration.
  • Previously: Claude Sonnet 4 added Sep 2025; this deepens autonomy.
• Claude accepts high-level goals, resolves files, iterates to completion.
  • Searches Apple docs autonomously; no step-by-step hand-holding needed.
• Visual interface testing: Claude captures SwiftUI Previews, iterates on design.
• Full project graph: SwiftUI, UIKit, Swift Data architecture understood pre-edit.
• MCP support: Claude Code users access Xcode Previews without leaving CLI.
• RC available now via Apple Developer Program; App Store release imminent.
