Apple Releases Xcode 26.3 With Support for AI Agents From Anthropic and OpenAI

After several weeks of testing, Apple today released Xcode 26.3, an update that allows developers to use tools like Anthropic's Claude Agent and OpenAI's Codex for app creation directly in Xcode.

macOS 26 Xcode
With support for agentic coding, Xcode can complete more complex app development tasks autonomously. Apple worked with Anthropic and OpenAI to configure their agents for use in Xcode and to ensure that AI models can access a full range of Xcode features.

Agents are able to create new files, examine code structure of a project, build a project directly and run tests, take image snapshots to check their work, and access Apple's full, up-to-date developer documentation.

Along with OpenAI and Anthropic models, Xcode 26.3 is compatible with any agent or tool that uses the open standard Model Context Protocol.

Xcode 26.3 is available for download today from Apple's developer website.

I have yet to see a skilled developer write better code than AI. In particular, the SotA models released since Opus 4.5
And no one who is a software developer believes you.

I have yet to see AI write acceptable code and I've said it before and I'll say it again, AI slows down a skilled developer. MIT even did a study on it showing that developers get slowed down between ~19% - ~22%.

Yes - but for those of us who know a bit of code but aren't 'skilled' it opens up a new world of possibilities. I don't claim to be a coder - heck I only really know Python from a class I took a few years back and then have been tinkering ever since.

AI has been a game changer for me. Instead of scratching my head over syntax or commands, I get to express my idea, have AI write the code and then iterate in ways I just couldn't do before. I don't really care if it's great code or not as long as I get the results I need. I've built simple but time saving tools this way in ways in minutes instead of days or weeks.

An analogy for me would be - can a skilled barista make a better coffee than a super-automatic? Of course! But is a super-automatic an option for decent coffee if you don't have barista skills - hell yes!

Until it gens code that doesn't compile and gives up. Been there. Done that.

Yep and I am a developer, just not an iOS or even Mac developer. But since getting Claude I’ve written my first Mac apps, signed up for the developer program and started writing iOS apps. These will never go on the App Store but I’m using them on my phone, solving use cases that I’ve had in my head for years.

Last weekend I built an app and backend that scrapes the commuter bus schedule and announces on my Sonos when a bus is 15 minutes away. That’s integrated with an MCP server that lets me tell Claude “I’m going to the office tomorrow” and it knows to set my Sonos alarm to the right time and start announcing buses the next morning. I wrote the iOS app to add a notification so it shows on my watch and keeps getting updates after I leave.

The Sonos part also tracks all the songs I play, including via SiriusXM and presents stats and a favorite function. Just last night I added MusicKit support so now that list of favorites syncs to my Apple Music as a playlist.

Nowadays if I see an app that does something I want but just slightly off, I just write a custom app exactly to my specs, and with no ads or subscriptions.
