    private let placeHolderImage = UIImage(named: "almond-milk") ?? UIImage()
    @State private var remoteImage: UIImage?
    var body: some View {
        Image(uiImage: remoteImage ?? placeHolderImage)
            .resizable()
    }
   
    private func downloadWebImage() {
        guard let url = URL(string: imageUrl) else {
            return
        }
        URLSession.shared.dataTask(with: url) {[self] (data, response, error) in
            if let data = data,
               let image = UIImage(data: data) {
                remoteImage = image

Hello, for doing asynchronous tasks (like fetching images), you should use the methods in your timeline provider, and attach the data to your timeline entry.
