Apple and Anthropic have unveiled the integration of Claude Sonnet 4 with Xcode 26, targeting developers who build applications for Apple platforms. By logging into a Claude account within Xcode, developers can leverage advanced coding intelligence features. This integration is available now to those running Xcode 26 on macOS, across all subscription plans that include Claude Code, such as Pro, Max, and enterprise-level offerings. The rollout spans globally wherever Xcode is supported through the Mac App Store.
Now generally available in Xcode 26: Developers can connect their Claude account to Xcode and power coding intelligence features with Claude Sonnet 4.

Claude Sonnet 4 powers a suite of tools directly inside the IDE, including:
- A natural language coding assistant
- Contextual project awareness for debugging and refactoring
- Documentation generation
- Code explanations
- Inline code modifications
These capabilities differentiate the offering from previous Xcode releases, which relied on Apple’s own code completion and analysis tools. Compared with other AI coding assistants, Claude Sonnet 4 offers conversation history, file attachments, and cross-platform usage limits, allowing developers to maintain workflow continuity between environments.
Early feedback from developers highlights the speed and contextual understanding of the assistant, particularly for large projects. Industry voices note that this move positions Apple to compete more directly with other AI-enabled IDEs. For Anthropic, this partnership with Apple marks a major deployment of Claude’s coding capabilities into a mainstream development workflow.
