iOS WidgetKit: remote images fails to load

Question

I\'m observing a bizarre thing: in the new widgets far too often remote images are not being displayed even though the image has been successfully loaded an

Yes, as mentioned by Konstantin, it is not supported to load images asynchronously. There are 2 options to load network image in widgets

1. Either fetch all the images in TimelineProvider and inject them to the views directly.

   OR

2. Use Data(contentsOf: url) to fetch the image. This way it still fetches them synchronously but the code is cleaner. Sample code -

   struct NetworkImage: View {
   
     private let url: URL?
   
     var body: some View {
   
       Group {
        if let url = url, let imageData = try? Data(contentsOf: url), 
          let uiImage = UIImage(data: imageData) {
   
          Image(uiImage: uiImage)
            .resizable()
            .aspectRatio(contentMode: .fill)
         } 
         else {
          Image("placeholder-image")
         }
       }
     }
   
   }
   

This view can simply be use like this -

NetworkImage(url: url)

Got it: it's simply not supported and you aim to load images inside TimelineProvider:
