Apple Foundation Models

Apple has released a Swift package that integrates Anthropic's Claude AI model into Apple's Foundation Models framework, allowing developers to use Claude as a server-side language model alongside Apple's on-device models. The package enables features like streaming, tool calling, and guided generation through the same API interface, with requests sent directly to Anthropic's servers and billed to users' Anthropic accounts. The integration requires iOS 27 or later and Xcode 27 (both in beta) and includes support for multiple Claude models with different capabilities.
