SwiftUI Tutorial: Interactive Holographic Card Animation

Build a Holographic Shine Effect in SwiftUI — Step-by-Step Tutorial
In this tutorial, we’ll create a smooth, drag-responsive holographic light effect on a SwiftUI card. This UI trick mimics the look of shiny trading cards — like Pokémon — by combining gestures, masking, gradients, and simple animations.
You’ll learn:
How to use DragGesture to control interactive movement
How to apply a dynamic mask for light reflection
How to layer SwiftUI views for complex visual effects
The core concepts behind clean, animated UI in SwiftUI
This is perfect for anyone learning SwiftUI and looking to add motion, polish, and depth to their designs — no 3D, no shaders, just smart layout and clean code.
