SwiftUISwift ChartsCore DataCombineCoinCap API
Problem
I wanted a CoinMarketCap-style tracker I understood end to end: live prices, a portfolio, and charts that feel native.
Build
SwiftUI with Swift Charts for the price and candle views, Core Data for persistence, and Combine to keep the UI reactive to live data from the CoinCap API.
Tech
SwiftUI, Swift Charts, Core Data, Combine, and the CoinCap API.
Result
Real-time prices, a working portfolio, and line and candle charts, all in a responsive, native-feeling UI.
