Crypto Trends is a test project showcasing a SwiftUI cryptocurrency trends application.
- The app displays the top 250 cryptocurrencies worldwide along with market statistics.
- Users can search for coins, sort them, and reload the data.
- Upon selecting a coin, users can view its statistics and price chart.
- The app uses Combine to fetch data and bind UI components reactively.
- Downloaded coin images are stored in the cache directory using FileManager.
- Users can select and add coins to their portfolio (wallet). Coin storage is implemented using Core Data.
- The app follows the MVVM pattern for clear separation of concerns.
CryptoTrends uses the CoinGecko to fetch the coins.
- SwiftUI: For building the app’s user interface.
