How can i get FLAC file metadata in Swift on ios 11?

i need to get metadata of an FLAC file. I tried following code :

let item = AVPlayerItem(url: URL(fileURLWithPath: path))
    let commonMetadata = item.asset.commonMetadata

    songInfo[ARTIST_NAME] = "Unknown"
    songInfo[GENRE_NAME] = "Unknown"
    songInfo[ALBUM_NAME] = "Unknown"
    songInfo[PLAY_COUNT] = "0"

    for metadataItem in commonMetadata {
        switch metadataItem.commonKey?.rawValue ?? "" {
        case "type":
            songInfo[GENRE_NAME] = metadataItem.stringValue
        case "albumName":
            songInfo[ALBUM_NAME]  = metadataItem.stringValue
        case "artist":
            songInfo[ARTIST_NAME] = metadataItem.stringValue
        default: break
        }
    } 

But this this on working for FLAC file . Any help will be appreciated
