Xcode 26.3 Is Now an MCP Server | First Look & Setup Guide

Xcode 26.3 just dropped with native agentic coding support. Both within Xcode and as an MCP server so external tools can also connect to it! This is a big deal for iOS/iPadOS/macOS developers using Claude Code or Codex—you can now connect your AI coding tools directly to Xcode. In this video, I give you my first impressions, show you what works, what doesn't, and walk you through the complete setup. ⏱️ TIMESTAMPS 0:00 – Intro & why this matters 0:30 – What's new in Xcode 26.3 Intelligence 1:00 – Demo: Claude Code + Codex MCP connection 2:00 – Limitations (no debugger, no simulator clicks) 2:30 – XcodeBuildMCP alternative 3:00 – Setup walkthrough 4:00 – xcode-select for multiple Xcode versions ⌨️ TERMINAL COMMANDS Claude Code: claude mcp add --transport stdio --scope user xcode -- xcrun mcpbridge Codex: codex mcp add xcode -- xcrun mcpbridge Point to Xcode 26.3: sudo xcode-select -s /Applications/Xcode.app/Contents/Developer Verify: xcodebuild -version 🔗 RESOURCES Download Xcode: https://developer.apple.com/xcode/ Apple Docs - External Agent Setup: https://developer.apple.com/documentation/xcode/giving-agentic-coding-tools-access-to-xcode XcodeBuildMCP (3rd party): https://github.com/cameroncooke/XcodeBuildMCP Book a call with me → https://yedatechs.com/#discovery-call Sponsorship inquiries → hi@yedatechs.com #Xcode #ClaudeCode #Codex #MCP #SwiftUI #iOSDevelopment #AgenticCoding
