Help with my code guys.. I'm really confused ...thanks

struct Playlist {

var title: String?
var description: String?
var icon: UIImage
var largeIcon: UIImage
var artists: [String] = []
var backgroundColor: UIColor = UIColor.clearColor()


init(index: Int) {
    let musicLibary = MusicLibary().library
    let playlistDictionary = musicLibary[index]

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


    let largeIconName = playlistDictionary["largeIcon"] as! String

    largeIcon = UIImage(named: largeIconName)!

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


    let colorDictionary = playlistDictionary["backgroundColor"] as! [String: CGFloat]

    backgroundColor = rgbColorFromDictionary(colorDictionary)

}

func rgbColorFromDictionary(colorDictionary: [String: CGFloat]) -> UIColor {

    let red = colorDictionary["red"]!
    let green = colorDictionary["greem"]!
    let blue = colorDictionary["blue"]
    let alpha = colorDictionary["alpha"]!

    return UIColor (red: red/255.0, green: green/255.0, blue: blue!/255.0, alpha: alpha)
}

Also you only initialized the large icon image and omitted the regularly sized icon.

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

Also you don't need to unwrap this line

largeIcon = UIImage(named: largeIconName)!
