What is Animatable Protocol?

The Animatable protocol allows you to customize how changes to your custom data types are animated in SwiftUI. By conforming to this protocol, you define a var animatableData: Self.AnimatableData property that SwiftUI uses to interpolate between the starting and ending values of your data during an animation. This enables smooth transitions for properties that aren't directly animatable by default, giving you fine-grained control over animation behavior.
