Print the names of all playlists:

import MediaPlayer

func printPlaylists() {
    let query = MPMediaQuery.playlistsQuery()
    print("Inside printPlaylists()")
    guard let result = query.collections else {return}
    print("Number of playlists: ", result.count)
    for playlist in result {
        let name = playlist.valueForProperty(MPMediaPlaylistPropertyName)!
        print("\(name), \(playlist.count)")
    }
}

// Running this in a playground doesn't print anything interesting.
printPlaylists()

This returns playlist directories as well, any idea how to filter those out?
