What I Learned
- SwiftUI app lifecycle (App, Scene, View)
- State management (@State, @AppStorage)
- Clean architecture (Views / Models / Networking)
- Working within API rate limits
Challenges & Solutions
- API rate limits: Finnhub's free tier allows 60 calls/minute. Implemented pagination and a "Load More" button instead of infinite scroll.
- Data source: Used a curated list of companies to balance coverage with API constraints.
