Claude Sonnet will ship in Xcode

Interesting to think about how Apple get to make product decisions based on Gatekeeper OCSP analytics now that every app launch phones home. They must know exactly how popular VSCode is.

Facebook got excoriated for doing that with Onavo but I guess it's Good Actually when it's done in the name of protecting my computer from myself lol

This won't make a dent. It still doesn't support any agentic operation.

The real news is when Codex CLI / Claude Code get integrated, or Apple introduces a competitor offering to them.

Until then this is a toy and should not be used for any serious work while these far better tools exist.

I just installed it—definitely not a toy.

Compared to stock Claude Code, this version of Claude knows a lot more about SwiftUI and related technologies. The following is output from Claude in Xcode on an empty project. Claude Code gives a generic response when it looked at the same project:

    What I Can Help You With

    • SwiftUI Development: Layout, state management, animations, etc.
    • iOS/macOS App Architecture: MVVM, data flow, navigation
    • Apple Frameworks: Core Data, CloudKit, MapKit, etc.
    • Testing: Both traditional XCTest and the new Swift Testing framework
    • Performance & Best Practices: Swift concurrency, memory management

    Example of What We Could Do Right Now

    Looking at your current ContentView.swift􀰓, I could help you:
    • Transform this basic "Hello World" into a recovery tracking interface
    • Add navigation, data models, or user interface components
    • Implement proper architecture patterns for your Recovery Tracker app

If a bunch of markdown files forced into the context is “knowing”, then yes. They are usually located at /Applications/Xcode-beta.app/Contents/PlugIns/IDEIntelligenceChat.framework/Versions/A/Resources/AdditionalDocumentation

You are free to point Claude Code to that folder, or make a slash command that loads their contents. Or, start CC with -p where the prompt is the content of all those files.

Claude Code integration in Xcode would be very cool indeed, but I might still stick with VSCode for pure coding.

No, this isn't a bunch of markdown files, has been in the works since at least May and has been dogfooded inside Apple [1]: "Apple Partners With Anthropic for Claude-Powered AI Coding Platform"
