Nothing is updating?

When I run the playlist browser app...my detail view controller does not display the title and description at all. The reason seems to be from not being able to get the data from the Playlist model. I downloaded your code and tried to run it, but there were several compiler errors...

init(index: Int) { let musicLibrary = MusicLibrary().library let playlistDictionary = musicLibrary[index]

    title = playlistDictionary["title"] as String!
    description = playlistDictionary["description"] as String!

    let iconName = playlistDictionary["icon"] as String!
    icon = UIImage(named: iconName)

    let largeIconName = playlistDictionary["largeIcon"] as String!
    largeIcon = UIImage(named: largeIconName)

    artists += playlistDictionary["artists"] as [String]

    let colorsDictionary = playlistDictionary["backgroundColor"] as [String:CGFloat]
    backgroundColor = rgbColorFromDictionary(colorsDictionary)

}

The errors are that AnyObject? is not convertible to type String. It wants me to force unwrap the as (as!)... Like I said the code was downloaded from your site and is untouched with the compiler errors. The same happened to me when I tried to follow Pasan. It forced me to add the bang at the end of each 'as' and now the title and description will not display in the Detail View Controller when I run the app. What is going on here?
