Answer 1

可以通过SwiftySVGAPlayer实现

首先使用CocoaPod安装SwiftySVGAPlayer:

pod 'SwiftySVGAPlayer'

然后，实现UIViewRepresentable使SwiftySVGAPlayer在SwiftUI中可用

import SwiftUI 
import SVGAPlayer
struct SVGAPlayerView:UIViewRepresentable
{
var url:URL

func makeUIView(context: Context) -> SVGAPlayer {
let player = SVGAPlayer()
let parser = SVGAParser()
parser.parse(with: url) { videoItem in
if let item = videoItem {
player.videoItem = item
player.startAnimation()
}
}
return player
}

func updateUIView(_ uiView: SVGAPlayer, context: Context) {
}
}

struct SVGAPlayerView_Previews: PreviewProvider {
static var previews: some View {
SVGAPlayerView(url: URL(string: "https://iulia.iwlive.club/ng/ring3d3.svga")!)
}
}
