Apple adds Claude and ChatGPT Codex support in Xcode 26.3

Now AI can code itself?

Apple announced today that, in the next update of Xcode 26.3, support for agentic AI would be increased. Previously in the original release of Xcode 26, ChatGPT and Claude were both available in Xcode, but this update allows for AI to run tasks and to take action inside the app. It essentially allows free roam on command and for AI to be able to work and write code autonomously. This can significantly improve and speed up workflows for developing apps.

This new update also includes support for the Model Context Protocol, an open standard that allows integration of any compatible AI agent or tool into Xcode. This is a great step towards improving on the developer relations that Apple has struggled with recently.

All of this still begs the question of why? Why do these tasks need to be automated, especially when many vibecoded (AI coded) apps' security systems are being exploited, since the checks that would have been performed by a human are not the same or nearly as thorough? While this is not the case for every app, and it isn't difficult for experienced developers to check over code before running and submitting apps, it still introduces a level of wariness that could be negated. Plus, if the whole point of using AI to code for us is that we need to do less work, then adding steps to check misses the point.

These concerns about AI in coding are not limited to Xcode's AI features and are widespread across the app development industry. It may just be a few more years before code written by AI can be trusted to be efficient, secure, and correct.

This is also not to say that AI in coding is inherently bad, as it still can speed up workflows. This is especially true for smaller tasks, where it is not only easier to see what errors there may be, but also where real people can focus on bigger, more difficult tasks that would require human intervention. Either way, it is still cool (albeit, nerve-racking) to see AI develop further each day, where now it can help developers code faster simply with the push of a button.

Xcode's new AI integrations with Claude and Codex from ChatGPT bring quicker workflows and improved AI capabilities to Xcode development. We will have to wait and see what Apple does soon.
