如何在SwiftUI中创建移动/活动虚线?

动画化 dashPhase StrokeStyle

struct ContentView: View {
    @State var phase: CGFloat = 0
    
    var body: some View {
        Rectangle()
            .strokeBorder(
                style: StrokeStyle(
                    lineWidth: 5,
                    dash: [10],
                    dashPhase: phase))
            .animation(
                Animation.linear(duration: 1)
                    .repeatForever(autoreverses: false),
                value: phase)
            .frame(width: 200, height: 200)
            .foregroundColor(Color.blue)
            .onAppear {
                phase = 20
            }
    }
}
