Foundation-Models-Framework-Lab

Why we included this project

Foundation Lab is a native macOS and iOS app for anyone building with Apple's on-device Foundation Models framework, and it pulls the scattered parts of LLM development into one place. Instead of juggling separate demos and console snippets, you get editable recipes, a prompt playground, and a run inspector in a single interface. That arrangement helps developers who want to see how model configuration, tool calling, and security settings behave on real hardware, as well as teams checking whether a particular adapter or runtime setup will fit before they commit. The Xcode 27 workshop and the adapter comparison workspace make it easy to change one variable and immediately see the effect on transcript, tool calls, timing, and token usage. Experiments are saved and can be exported as Swift, so the app stays useful as a production reference once you move past the tutorial stage.
