Apple's iOS 27 Foundation Models Framework Turns Every iPhone App into an Agent Runtime
Apple's WWDC26 introduced the Foundation Models framework, a native Swift API that lets any iOS app work with Apple's on-device models, Anthropic's Claude, Google's Gemini, or any provider conforming to the Language Model protocol. Combined with Dynamic Profiles for runtime model swapping, a rebuilt Siri AI with deep personal context, and free Private Cloud Compute access for small developers, Apple is positioning iOS as a model-agnostic agent orchestration layer for 2+ billion active devices.
