SwiftUI:如何制作 Lottie 动画循环？

Question

通过赋予它自己的观点，我已经成功地将 Lottie 应用到我的程序中。虽然一旦被调用，动画只播放一次。我将如何使动画循环？谢谢你。
LottieView(与 Lottie 一起查看。)

import SwiftUI
import Lottie

struct LottieView: UIViewRepresentable {
    typealias UIViewType = UIView
    var filename: String
    func makeUIView(context: UIViewRepresentableContext<LottieView>) -> UIView {
        let view = UIView(frame: .zero)
        
        let animationView = AnimationView()
        let animation = Animation.named(filename)
        animationView.animation = animation
        animationView.contentMode = .scaleAspectFit
        animationView.play()
        
        
        animationView.translatesAutoresizingMaskIntoConstraints = false
        
        view.addSubview(animationView)
        
        NSLayoutConstraint.activate([
            animationView.widthAnchor.constraint(equalTo: view.widthAnchor), animationView.heightAnchor.constraint(equalTo: view.heightAnchor)
        ])
        
        
        return view
    }
    
    func updateUIView(_ uiView: UIView, context: UIViewRepresentableContext<LottieView>) {
        
    }
    
    
    
    
}

ContentView 中的当前实现:

     HStack {
            
            if isScroll {
                LottieView(filename: "swipeLeft").frame(width: 200, height: 200)
                        .padding(.top, 500)
                        .padding(.leading, 100)
                       
                                 }
            Spacer()
        Button(action: {
           SCLAlertView().showInfo("How to use:", subTitle: "Scroll across the screen to view panels. Then press on a panel to view more information.")
        }) {
            Image(systemName: "info.circle")
            .padding(.trailing, 5)
                .padding(.top, 400)
                       
        }
        
    
        }

您可以为播放调用设置循环行为。在 makeUIView(context:) 中添加此代码

animationView.loopMode = .loop
