Problem with code in Algorhythm in Building an iOS App, even though it's exactly as the instructor typed it.

I'm following along in Build a Playlist Browser and learning more about Swift, but I'm very confused right now. My code won't build because of two errors that make no sense to me:

THIS ONE WORKS:

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

But this one, same syntax, shows an error: (use of unresolved identifier 'largeIcon')

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

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

The error for the following says: expected member name or constructor call after type name

let colorsDictionary = playlistDictionary["backgroundColor"] as [String: CGFloat]
backgroundColor = rgbColorFromDictionary(colorDictionary: [String : CGFloat])
        //these two errors don't make sense, as they are exactly like the video...

Any ideas?

You are having this problem in the second case : because you didn't declare the if largeIcon is a constant or variable and the same thing for artists

That's exactly it! I just discovered it (2 minutes ago). largeIcon was left out of the group of variables. Yay! I figured it out. The var artists is declared.

But I still haven't figured out the next one: rgbColorFromDictionary...

Nevermind. Got it. Left the "s" off colorsDictionary. I'm getting this down! :)
