Beginning vibe coding in Xcode

Apple recently added vibe coding capabilities to Xcode (starting version 26.3) - largely by first building several MCP servers on top of Xcode and then enabling Claude Code and ChatGPT Codex to use these MCP servers to manipulate pretty much anything you want within Xcode. I am using paid Plus plan of ChatGPT and using Codex with Xcode right now. I am very impressed with what I’ve seen so far. In my experience it mostly just works. With not too much overview or interference, it gets pretty much everything right. I recently used it to add a Yearly and Daily exports to my app, Incompare, and it was a breeze. Took me all of maybe 20 minutes or less to provide a good description, test it, iterate on it a couple time and there you go. Super cool.

You pretty much explain to the agent (exposed via a chat interface) and it goes about doing its thing. It mostly get it right the first time even when the description isn’t all that precise or detailed. You can usually get pretty much anything relatively straightforward done over a couple of iterations.

in Xcode, which is usually quit slow to see advancements, this feels like complete magic.
