Apple today released the latest version of Xcode 26, introducing several new features that developers can take advantage of.
ChatGPT in Xcode now supports GPT-5, so developers can choose to start new conversations with GPT-5 or GPT-4.1. GPT-5 is the new default option, with two models to select from. GPT-5 is optimized for quick, high-quality results that Apple says will work for most coding tasks.
For more difficult tasks, developers can select GPT-5 (Reasoning), which spends more time thinking before providing a response.
Claude in Xcode is now available in the Intelligence settings panel in the Xcode app, so users can add their existing paid Claude account and use Claude Sonnet 4 for coding tasks.
When Xcode 26 officially launches, the app will support coding help from either ChatGPT or Claude, providing users with the option to use their favorite chatbot. Developers are also able to bring API keys from other providers or run local models on Apple silicon Macs.

I've gotten into a habit of using LLMs to validate things, reduce boiler plate, write tests, etc.
I use Claude code in the project folder to find things, make lists, etc. I have colleagues who submit whole PRs using AI tools and to date have resulted in a lot of re-work, from things like using print statements instead of using a logger, or adding singletons, ignoring existing dependencies, force unwraps and the comment puke also adds so much nonsense to what should nowadays be simple code, its kind of annoying.
I had high hopes for AI coding after the early GPTs but its cooled off a bit, I use it all day on one shot tasks and its great but it really falls apart quick.
Though, if one does not give up bicycle completely and remain strong, while still using the motorbike for things that need to be fast, that might be the best of both worlds.
