```
var songs = MPMediaQuery()
var localSongs = songs.items
songList = NSMutableArray(array: localSongs)

tableView.reloadData()

var song = MPMediaItem(coder: songList[0] as NSCoder)

var currentItem = AVPlayerItem(URL: song.valueForProperty(MPMediaItemPropertyAssetURL) as NSURL)

player.replaceCurrentItemWithPlayerItem(currentItem)

player.play()

var songTitle: AnyObject! = song.valueForProperty(MPMediaItemPropertyTitle)

songName.text = songTitle as? String

sliderOutlet.value = Float(player.currentTime()) // <<-Error here

```

I'm building a music player and I want a slider to show the duration of the song, but I get this error

I think the problem is converting CMTime to Float.
