Claude can now plug into Apple’s Foundation Models framework
Anthropic released a Swift package that lets Apple apps use Claude through Apple’s framework. Claude can act like a server-based inside the same system Apple uses for its . Developers can use the same flow to ask Claude for answers, stream replies, request , and use .
Requests go from the app to the Claude API, and Apple does not see the prompts or responses. Billing goes to the developer’s Anthropic account under normal API pricing. During development, an app can use a directly, but shipped apps should use a proxy because a key inside an app can be extracted and abused.
Apple’s is fast, private, and works offline, while Claude is meant for harder tasks that need longer context, stronger reasoning, web search, or code execution. The package is still beta and targets iOS 27, macOS 27, visionOS 27, watchOS 27, and Xcode 27 betas, so the API may change before full release.
Key points
- Claude for is a Swift package for using Claude inside Apple’s framework.
- Apps can switch between Apple’s and Claude through the same style.
- Requests go directly to the Claude API, not through Apple.
- Production apps should use a proxy instead of shipping a inside the app.
- Claude is positioned for longer context, harder reasoning, web search, and code execution.
