我必须在 else 正文中编写什么才能从 firebase 存储中检索图像并将其显示在 UI 中？

public func downloadFile(url: String){

    var img: Image?

    let storage = Storage.storage()
    let storageRef = storage.reference()
    let imageRef = storageRef.child("Wallpapers/Cars/Wallpaper1.jpg")
    imageRef.downloadURL { (url, err) in
        if let err = err{
            print("Error! Unable to download")
        }
        else{

        }
    }

}
