SwiftUI:用动画改变定时器上的图像

import SwiftUI

struct ContentView: View {
    @State private var imageRotationAngle: Double = 0

    let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()

    var body: some View {
        Image("imageName")
            .resizable()
            .scaledToFit()
            .rotationEffect(.degrees(imageRotationAngle))
            .animation(.easeInOut(duration: 1))
            .onReceive(timer) { _ in
                withAnimation {
                    imageRotationAngle += 45
                }
            }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
