A concept to more easily define simple keyframe / multi-step animations in SwiftUI, without:

Defining an @State value for each property to be animated
Using asyncAfter

The approach has gone through a few very different iterations (see commit history), but there's still room for improvement. PRs and discussion are welcome!

Example Usage

struct ContentView: View {
    var body: some View {
        VStack {
            Image(systemName: "globe")
                // This animation will start as soon as the view appears.
                .animate(
                    .start {
                        $0.opacity = 0.5
                    },
                    .at(2) {
                        $0.opacity = 1
                        $0.offsetY = 50
                        $0.scale = 1.5
                    }
                )
        }
    }
}

Minimum Requirements

iOS 15 / macOS 12 / tvOS 15 / watchOS 8
Swift 5.7 (Xcode 14)

To-Do

Support for animation of arbitrary properties (via closure?)

Notes

Properties are animated in the order that their view modifiers are applied (see AnimationViewModifier.swift)
