Current public API, use Image or UIImage as a placeholder, which is previouslly in UIKit world. But is not suitable in SwiftUI world.

For SwiftUI, the view is a command to build real view on the screen, there are no subviews like UIKit. So, putting a Image is not so comfortable.

For example, if I want to add a grey-rounded corner placeholder, I don't need to use a Image, but a native Rectangle view.

Usage code:

WebImage(url: url) { Rectangle() .foregroundColor(.gray) }
