foundation-models-on-device

Patterns for integrating Apple's on-device language model into apps using the FoundationModels framework. Covers text generation, structured output with @Generable, custom tool calling, and snapshot streaming — all running on-device for privacy and offline support.

Stream structured responses for real-time UI with PartiallyGenerated types:

| On-device execution | Privacy — no data leaves the device; works offline | | 4,096 token limit | On-device model constraint; chunk large data across sessions | | Snapshot streaming (not deltas) | Structured output friendly; each snapshot is a complete partial state |
