Thread 1: breakpoint 1.1

I did all the code right I believe. But at this line:

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

there would be a breakpoint and I don't know why, if anyone comes into same problem here?

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 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 = rgbFromDictionary(colorsDictionary)

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

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

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

I haven't taken this lesson but if i understand your question correctly your code is halting because its coming to a breakpoint. A breakpoint is a terribly annoying feature in Xcode that you can click on by accident which causes the compiler to halt when it reaches that particular line of code. On the gutter to the left of your code, you can click on the number of the line and create a breakpoint which is for debugging purposes. Look for any rectangles with a pointed end in the gutter to the left of the line in question. you can click and drag them off the gutter then let go to get rid of them. they will "poof" and disappear
