Thanks for the PR! However, there are a number of improvements that need to be made before we can accept it.

First, it should offer an API surface as similar as possible to the newly added AsyncImage. Ideally users would just need to change the type of the view to migrate between the types.

Second, it needs to include API that allows users to progressively customize the underlying image loading behavior. This would start with simply loading a URL like AsyncImage to being able to take a full ImageDownloader instance.

Third, it should not use AnyView but instead embrace generics to allow the placeholder to be fully defined by a ViewBuilder.

@Alexroar any update on this? Hoping for some native SwiftUI support so we can utilize this library in our app.
