WWDC26: Build agentic app experiences with the Foundation Models framework | Apple
Apple's WWDC26 Foundation Models framework adds DynamicProfile APIs and an open-source Utilities package for building agentic app experiences.
“You can think of this as swapping hats, or switching agents.”
At WWDC26, Apple introduced DynamicProfile APIs and an open-source Foundation Models framework Utilities package that let developers build agentic experiences by switching between models (on-device SystemLanguageModel and server-based PrivateCloudComputeLanguageModel), managing context windows, and composing reusable instruction sets. This matters because it pushes structured agent orchestration and context engineering into Apple's native developer stack, signaling deeper platform-level investment in on-device and hybrid AI agents.
