You don't need an animation library to add a simple effect to your SwiftUI app. Create it yourself with SwiftUI. This repo inspires you to add helpful and expressive SwiftUI animations like loading/progress, looping, on-off, enter, exit, fade, spin, and background animations to your next project. The repo also contains tremendous spring animations.
