Hello,

I came across this issue while following the tutorial for Animating Gestures from day 33. The code tries to animate a drag gesture, wherein the individual letters from the text are attached with an increasing delay.

The animation works fine only for the first drag motion. After that, the animation stops working completely until I let go (where the letters go back to their original position and the color change is animated).

I am using using Xcode 15.0 and iOS 17.0

However, upon setting the minimum deployment parameter to iOS 15.0 in the target settings, the animation works as expected and as shown in the tutorial.

Has anyone noticed this behaviour and has an explanation for it? Thanks in advance!

Code from the tutorial

struct ContentView: View {
    let letters = Array("Hello, SwiftUI")
    @State private var enabled = false
    @State private var dragAmount = CGSize.zero

    var body: some View {
        HStack(spacing: 0) {
            ForEach(0..<letters.count, id: \.self) { num in
                Text(String(letters[num]))
                    .padding(5)
                    .font(.title)
                    .background(enabled ? .blue : .red)
                    .offset(dragAmount)
                    .animation(
                        .default.delay(Double(num) / 20), 
                        value: dragAmount
                    )
            }
        }
        .gesture(
            DragGesture()
                .onChanged { dragAmount = $0.translation }
                .onEnded { _ in
                    dragAmount = .zero
                    enabled.toggle()
                }
        )
    }
}
