Welcome to this lesson on SwiftUI Animation! This guide will get you started animating all sorts of SwiftUI views, from simple transitions to complex, interactive effects.
So, why add animation to your apps? While a static app can be functional, animation brings it to life. Good animation isn’t just decoration; it’s a powerful form of communication. It can guide a user’s eye to what’s important, provide satisfying feedback for an action (like a button tap), and make the entire user experience feel more polished, intuitive, and alive. With SwiftUI, the framework does most of the heavy lifting, making it surprisingly easy to implement beautiful, performant animations.
Before diving in, it’s important to understand a simple definition of animation. For our purposes:
Animation is a change in value or state over time.
If a view’s position changes from point A to point B instantly, it simply appears at the new location. However, if that same position change happens over a perceivable period, like half a second, that’s the kind of smooth animation we’re aiming for.
