Claude Code is powerful for iOS development, but it lacks access to Apple documentation because they are locked behind JavaScript. Here are two solutions.
Tip #1: Sync Xcode’s Documentation Locally
Xcode includes the same documentation that powers their Apple Intelligence, for Code Assist in Xcode 26. Copy it to your project so Claude can reference it.
rsync -av --include='*/' --include='*.md' --exclude='*' \
/Applications/Xcode.app/Contents/PlugIns/IDEIntelligenceChat.framework/Versions/A/Resources/AdditionalDocumentation/ \
./Docs-xcode/
With that, you gain 20+ markdown files for Claude to use. I suppose more will be added for Xcode AI to work better too.
You will also want to add the dir to .gitignore, and probably mention in .claude/CLAUDE.md on the additional, secret, documentation.
Tip #2: Use Sosumi MCP for Live Documentation
Claude will have error 404 or others when trying to use web search for Apple docs, because the docs are rendered with JavaScript and Claude is incapable to fetch them, yet.
The solution is sosumi MCP.
claude mcp add sosumi https://sosumi.ai/mcp
Ask Claude to search or fetch docs:
- “Use sosumi to search for @Generable macro”
- “Fetch the Foundation Models documentation”
Sosumi will respond in markdown versions 🐳
