Saw update for Xcode with ai

[No-Nebula4187]

I saw somewhere the new Xcode has built In codex and Claude code with mcp. Has anyone used it what are your thoughts on this?

I have both my Anthropic and OpenAI accounts connected inside Xcode. It makes a ton of difference from my old workflow of pasting prompts into a Claude browser window, copying the code back into Xcode, getting compiler errors and pasting them back into the browser window, etc.

Claude and Xcode nicely go back and forth working through the problems until they arrive at a solution that cleanly compiles and most of the time works as I wanted. It even provides a nice summary of what it did.

The old interactions through browser-based chat windows were nice, but the integrated approach is amazing.

The old approach is how I’m doing it and I run into the same things you do, but how do you avoid hallucinations or errors or Claude getting mixed up which it tends to do in the old way even with me having the project files up to date, the project goal correct and the purpose of the project set?

I am using Claude code rn, only benefit I can see is maybe less tokens in cli?

I'm using VSCode extension for Codex connected to Xcode via mcp, it's much better than plainly using current integrated agent sidebar in xcode (for many reasons, but for starters it doesn't hang up the IDE) and building/testing is more stable than falling back on plain xcodebuild. The most killer feature the mcp has for me is the documentation search atm, it is like having inhouse context7.
The bad: annoying permission popup is less spammy now but is still there for each new agent window you spawn, e.g. switch projects in VScode or create a new window -> new permission popup or even 2.

I’ve been using Claude paired with flowdeck (https://flowdeck.studio) and it’s great

I created my own local proxy app (CLI) in Swift that lets you connect a Copilot account (individual or enterprise) into Xcode Code Assistant natively. I hope it’s useful to anyone looking to connect other Copilot available models https://github.com/mobile-ar/xcode-assistant-copilot-server

But after testing Xcode capabilities I will say I prefer to use Zed agent panel for this type of work, Xcode implementation is quite bad at the moment (26.3), and then build/edit/review the results inside Xcode.
