Xcode 26 Beta 7: GPT‑5 and Claude Sonnet 4 Integration

Apple has released Xcode 26 beta 7, which expands the IDE’s “Coding Intelligence” capabilities by allowing developers to integrate external large language models directly in Xcode. The update adds support for OpenAI’s GPT‑5 and Anthropic’s Claude Sonnet 4, letting developers use these models for code generation, assistance, and other AI-driven workflows.

Key points

• Direct integration of OpenAI GPT‑5 and Anthropic Claude Sonnet 4 into Xcode’s Coding Intelligence features.
• Developers can connect paid Anthropic accounts via the Intelligence settings panel and choose GPT‑5 variants optimized for speed or reasoning.
• Option to use hosted APIs (OpenAI/Anthropic) or local models on Apple silicon for on-device AI assistance.

Notes for developers

If you rely on AI-assisted coding tools, check the Intelligence settings in Xcode to connect your OpenAI or Anthropic account, choose preferred model variants, or configure local models on Apple silicon. As always, test outputs and review generated code carefully before merging into production projects.
