我正在尝试检索播放列表的艺术品（而不是歌曲的艺术品）。Apple 音乐应用程序可让您为播放列表创建图像，但我似乎无法访问它。

这可能吗？MPMediaItemPropertyArtwork 未列为播放列表属性键之一。

我正在尝试以下操作：

let playlistItems: [MPMediaPlaylist] = playlistQuery.collections! as! [MPMediaPlaylist]

    for playlist in playlistItems {

        let artwork = playlist.value( forProperty: MPMediaItemPropertyArtwork ) as? MPMediaItemArtwork
        let sizeforArtwork = artwork?.bounds.size
        let artworkImage = artwork?.image(at: sizeforArtwork!)

        let playlistName = playlist.value( forProperty: MPMediaPlaylistPropertyName ) as! String

        let info: PlaylistInfo = PlaylistInfo(
            playlistTitle: playlistName,
            playlistImage: artworkImage
        )
        playlists.append(info)
    }

和

struct PlaylistInfo {
var playlistTitle: String
var playlistImage: UIImage?
}

var playlists: [PlaylistInfo] = []
