让用户将多个图像添加到SwiftUI视图

import SwiftUI

struct ContentView: View {
    let imageUrls = [
        "https://your-cos-bucket.cos.ap-guangzhou.myqcloud.com/image1.jpg",
        "https://your-cos-bucket.cos.ap-guangzhou.myqcloud.com/image2.jpg",
        "https://your-cos-bucket.cos.ap-guangzhou.myqcloud.com/image3.jpg"
    ]
    
    var body: some View {
        VStack {
            ForEach(imageUrls, id: \.self) { imageUrl in
                if let url = URL(string: imageUrl) {
                    AsyncImage(url: url)
                        .frame(width: 200, height: 200)
                        .aspectRatio(contentMode: .fit)
                }
            }
        }
    }
}

struct AsyncImage: View {
    @StateObject private var imageLoader = ImageLoader()
    private let url: URL
    
    init(url: URL) {
        self.url = url
    }
    
    var body: some View {
        if let image = imageLoader.image {
            Image(uiImage: image)
                .resizable()
        } else {
            ProgressView()
                .onAppear {
                    imageLoader.loadImage(from: url)
                }
        }
    }
}

class ImageLoader: ObservableObject {
    @Published var image: UIImage?
    
    func loadImage(from url: URL) {
        URLSession.shared.dataTask(with: url) { data, response, error in

                }
