How can I show AVPlayerMetaData such as commonIdentifierArtist for the artist and commonIdentifierAuthor for the author, in AVPlayer for TVOS?

edit

You can use the following code to retrieve the metadata of the current item being played by the AVPlayer:

guard let currentItem = player.currentItem else { return }

for item in currentItem.asset.commonMetadata {
    if let identifier = item.commonKey?.rawValue, let value = item.value {
        print("Identifier: \(identifier) | Value: \(value)")
    }
}

This will print out all the available metadata keys and their corresponding values for the current item. You can then filter the metadata to retrieve the specific ones you need, such as commonIdentifierArtist and commonIdentifierAuthor.

if let artist = currentItem.asset.metadata(forFormat: AVMetadataFormatiTunesMetadata)[0].value(forKey: "artist") as? String {
    print("Artist: \(artist)")
}

if let author = currentItem.asset.metadata(forFormat: AVMetadataFormatiTunesMetadata)[0].value(forKey: "author") as? String {
    print("Author: \(author)")
}

Note that the commonIdentifierArtist and commonIdentifierAuthor keys may not be available for all items, so you may need to check for their existence before retrieving their values.
