I’m trying to implement a cache for storing remote videos in my SwiftUI app.

The main approach I found so far is the accepted answer in this thread: Is it possible to cache Videos? IOS – Swift

However, when I try to implement it, the video does not load:

VideoPlayer(player: player)
    .onAppear {
        CacheManager.shared.getFileWith(stringUrl: videoURL) { result in
            switch result {
            case .success(let url):
                self.player = AVPlayer(url: url)
                self.player?.play()
            case .failure:
                print("Error")
            }
        }
    }

For context, printing the URL from CacheManager gives file:///var/mobile/Containers/Data/Application/2F12CCE9-1D0C-447B-9B96-9EC6F6BE1413/Library/Caches/filename (where filename is the actual filename).

And this is what the video player looks like when running the app.

If I was to play directly from the videoURL, then there would be no issues and the video plays. But I would like to cache it as well. So is there an issue with my implementation of the code? Is the accepted answer from the old thread actually invalid/outdated and no longer works with current iOS versions? Does anyone have an alternative method for caching videos?
