Apple Introduces Claude for Foundation Models as Server-Side Language Model

Jun 15, 2026

AI Summary

Apple has launched a Swift package called Claude for Foundation Models, enabling developers to integrate the Claude language model into their applications. This package allows for server-side processing while maintaining user privacy, as requests are sent directly to the Claude API without Apple intermediating.

Claude for Foundation Models is a Swift package that integrates the Claude language model into Apple's Foundation Models framework.
The package conforms to the LanguageModel protocol, allowing developers to use the same API for both Claude and Apple's on-device model.
Requests are sent directly from applications to the Claude API, ensuring that Apple does not access user prompts or responses.
The package is currently in beta and targets the Foundation Models server-side language model API introduced in the OS 27 betas.
Developers can switch between using Claude and Apple's on-device model by passing the desired model to each session.
The package includes features for structured output, server-side tools, and error handling, enhancing the capabilities of applications using the Claude model.
To use the package, developers need to add it to their Package.swift file or Xcode project and configure it with their Anthropic API key.
The package is licensed under Apache 2.0, and bug reports can be submitted through GitHub issues during the beta period.
