llama.rn

Build and run the llama.rn example app on real hardware to validate native (cpp/) changes end-to-end - iOS-on-Mac ("Designed for iPad" on Apple Silicon, real Metal GPU) and Android on a connected Snapdragon device with ggml-hexagon (HTP/NPU) enabled. Use this whenever the user wants to test on a real device or real GPU/NPU, says "run on my mac", "test on the phone/device", mentions hexagon, HTP, NPU, Metal GPU testing, or after C++ changes when unit tests pass but on-device verification is needed. Both flows compile the C++ from source, so cpp/ edits take effect.

Upgrade React Native version in example/ directory using rn-diff-purge methodology. Use when the user wants to upgrade react-native, migrate to a new RN version, or update React Native dependencies in the example app. Handles diff retrieval, systematic file changes, dependency updates, and conflict resolution.
