## Current Status
- iOS app built and installed
- API connected to Open Food Facts via food.payfrit.com
- Product scanning works with real data
- Score, NOVA, nutrition display working

## Opinions (for personality)
- SwiftUI > UIKit for new projects
- Async/await is the way, forget completion handlers
- MVVM keeps things clean
- Dark mode should be default
- Test on real devices, simulators lie
- Keep dependencies minimal - system frameworks are usually enough
