CryptoTracker

A small macOS app, built with SwiftUI, that lists crypto prices in a clean dark interface.

What it is

A SwiftUI practice project: one screen that shows a few cryptocurrencies and their prices, built to get comfortable with how Apple's declarative UI works.

Right now it's a UI prototype. The prices are sample values written in the code, not live data. The interface, layout and data model are done, and connecting a real price API is the next step (see the roadmap below).

What I learned building it

• Declarative layouts with ZStack, VStack and HStack instead of positioning views by hand.
• Modeling data with an Identifiable struct, so ForEach can render one card per coin.
• Apple's visual language: SF Symbols for the icons, a translucent .ultraThinMaterial for the cards, and shadows and gradients for depth.
• Separating the model from the view, so swapping sample data for API data only touches one place.

Run it

You need a Mac with macOS Sonoma 14 or newer and the Swift toolchain (comes with Xcode or the Command Line Tools).

git clone https://github.com/Santi2307/CryptoTracker-Pro.git
cd CryptoTracker-Pro
swift run

To edit it with live previews, open the folder in Xcode (File → Open… and select Package.swift).

How it's organized

Sources/CryptoTracker/
├── CryptoTrackerApp.swift   App entry point and window
└── ContentView.swift        The coin model, sample data and the list UI

Roadmap

• Dark UI with one card per coin
• Live prices from the CoinGecko API, refreshed every minute
• 24-hour change in green or red next to each price
• Price history chart with Swift Charts
• Choose which coins to follow (watchlist)
• iPhone version
