xlate sensorlab

Expo app with custom native modules for sensor processing. Uses a custom dev client (not Expo Go) because we integrate Swift and Rust code.

Quick Start

Prerequisites:

• ✅ Node.js, Xcode, CocoaPods
• ✅ Rust toolchain
• ✅ iOS device with Developer Mode enabled

Setup:

cd pycontroller
npm install
cd ios && pod install && cd ..
sh rustcore/build-ios.sh  # Required - builds Rust libs

Run on device:

cd pycontroller
npx expo run:ios --device

Requires your iPhone connected via USB with Developer Mode enabled. The custom dev client installs automatically on first run.

Native code changes: Rebuild the dev client with npx expo run:ios --device.

CI/CD

New GitHub releases trigger ios.yml to automatically build and submit to TestFlight.
