SwiftUI Component Design & Animation in a Stock Market App

Learn how to build clean, scalable, and animated SwiftUI apps by mastering the art of component-based design and reusable architecture. In this course, you’ll develop a complete stock tracking interface while learning how to decompose views, implement protocol-based styling, and create smooth animated visualizations for real-time stock data.

We start with the foundation of SwiftUI’s declarative structure and walk through how to break a large view into smaller, focused components. You’ll learn multiple methods to structure your views:

• Using computed properties to isolate static subviews

• Creating custom view structs for reusable building blocks

• Leveraging generic views to accept flexible, styled content

• Using @ViewBuilder functions for lightweight layout wrappers

• Applying view extensions and protocols for consistent style systems

You’ll implement protocol-based styling by creating view protocols with extension methods that encapsulate layout and visual rules. This lets your views apply consistent designs—like card layouts or themed backgrounds—without duplicating modifiers.

Later in the course, we integrate chart and progress view animations. You’ll build a radial progress indicator and animate it using @State, @Binding, and @Published properties tied to a ViewModel. This teaches you how to sync animations with live data updates.

Whether you're building stock apps or any data-driven UI, this course gives you a repeatable system for crafting modular, visually polished, and interactive SwiftUI apps.
