Why is Xcode prompting me to unwrap?

I have been following the tutorials for iOS Development. I copied the code over exactly how Pasan did. Like this:

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

But, an error comes up stating the following:

'AnyObject?' not convertible to 'String!'; did you mean as! to force downcast?

Why am I getting this error and Pasan is not in his tutorial when he has the same exact code? Is there a problem in my code somewhere else? I am unsure if it will affect the performance in the future of my app.

Please help.

Thanks in advance.

Pasan may have produced this video with an earlier version of Xcode. There is a good post on the swift blog covering this very topic.
