ios – How to preview selected video from the gallery

I am trying to display my selected video as preview before it uploaded, just like my preview of the image is being shown in the image below the image preview

I am not able to display my selected video in screen as preview because of these errors.

Result of ‘VideoPlayer’ initializer is unused

 VideoPlayer(player: AVPlayer(url: url))

 @State var url: URL?
 var body: some View {
 if let url {
                            VideoPlayer(player: AVPlayer(url: url))
                        }

Full Code

import AVKit
struct CreateView: View {
   
    @State var url: URL?
    private var user: User? {
        return UserService.shared.currentUser
    }
    var body: some View {
