Apple LLM Test App

A test application for evaluating Apple's on-device large language model and the Foundation Models framework.

This iOS app is our internal testbed for Apple Intelligence and the Foundation Models framework. We use it to benchmark on-device inference quality, latency, and tool-use behavior across real-world prompts, and to validate patterns before shipping them into client projects.
