I am developing Widgets for iOS and I really don't know how to download images for the widgets.

The widget currently downloads an array of Objects, and every object has a URL of an image. The idea is that every object makes a `SimpleEntry` for the `Timeline`.

What's the best way of achieving this? I read that Widgets shouldn't use the `ObservableObject`. I fetch the set of objects in the timeline provider, which seems to be what Apple recommends. But do I also download the images there and I wait until all are done to send the timeline?

Any advice would be very helpful,
