Xcode 26 with GPT-5 and Claude is there-beta for testing

The rumors were right: Apple also allows developers to use Anthropics Claude as coding assistants in the future. The function is part of the seventh beta of Xcode 26that for members of members of Apple’s development opera program was published. In addition to Claude, GPT-5 is now also made available from Openai.

Reasoning model from GPT-5-but only “low”

The chatt-based assistant in Xcode previously dominated GPT-4.1. In the future, GPT-5 will be the standard model of Openaai, but it is also possible to switch back to GPT-4.1, after all, GPT-5 is not undisputed for programming. GPT-5 is “optimized for fast, high-quality results”, writes Apple in the Xcode 26 Beta-7 package insert. “That should work well for most coding tasks.” However, it is also praised to switch to the Reasoning model from GPT-5.

“This takes more time to think, but can provide more precise results for more complex programming tasks.” Apple indicates that GPT-5 runs without any reasoning at the “minimal” Reasoning level, GPT-5 with Reasoning at the Reasoning Level “Low”. This means that the full follow -up performance via Xcode is not available – with the Chatgpt app for macOS, however, should work. Openai had already developed an Xcode integration last year.

Paid account from Claude necessary

Claude in Xcode is based on Sonnet 4 and can be called up via the “Intelligence Settings” panel. It is not free: users have to store their payment account at Anthropic. It remains unclear whether Opus 4 is also supported-code references had previously been found. If Xcode 26 appears, it should continue to be possible to integrate third models via their API. After all, Apple also wants to support local models that are becoming increasingly popular if the Mac is sufficiently performant.

Further speculation that Claude could soon be integrated into Siri or system across the system, as is known from Chatgpt, did not initially be confirmed. Xcode 26 Beta 7 also runs under MacOS 15 alias Sequoia. However, the AI ​​support does not seem to be active there. Users also need a beta of MacOS 26 alias Tahoe. There is also a hurdle here: it is not allowed to run in a VM, since the Apple intelligence operator cannot be activated there
