Overview

• Strings in Xcode 26 beta 7 reference Anthropic account support and explicitly name Claude Sonnet 4.0 and Opus 4.
• ChatGPT remains the only first‑party model available in Xcode, and Apple has not announced native Claude support.
• The references appear inside the new Intelligence feature that broadens the former Swift Assist to include Apple models, built‑in ChatGPT, and pluggable third‑party or local models.
• Server‑side configuration cited by 9to5Mac indicates Claude could be offered as an option in system Writing Tools or as a Siri alternative, which remains unconfirmed.
• The findings align with Bloomberg’s May report of internal Claude testing and highlight Apple’s shift toward external AI partnerships.
