Create a study guide for me based on all things related to Foundation Model Framework

Here's a study guide on the Foundation Models Framework based on the content presented at WWDC:

Overview of the Foundation Models Framework

1. Introduction to the Framework

   • The Foundation Models Framework provides access to an on-device large language model with a Swift API. It is available on macOS, iOS, iPadOS, and VisionOS, allowing for enhanced app features like personalized search suggestions and itinerary generation, all while maintaining user privacy since it runs offline and is built into the operating system.
   • Meet the Foundation Models framework

2. Key Features

   • Guided Generation: Allows for structured output in Swift, enabling developers to define data structures that the model can generate automatically.
   • Tool Calling: Lets the model autonomously execute code defined in your app, enhancing its capabilities.
   • Stateful Sessions: Built around the concept of sessions, allowing for custom instructions to guide the model's responses.
   • Streaming APIs: Provides options for displaying responses incrementally, improving user experience by reducing perceived latency.

Deep Dive into the Framework

1. Sessions and Generable

   • Sessions are central to interacting with the model, allowing for text generation and more complex outputs using the Generable feature, which helps in obtaining structured data.
