Not sure Why?

I use the same code in xcode and I get the correct answer. Help!

dictionaries.swift 
let currencies = ["US":"Dollar","UK":"Pound","JP":"Yen"]
let ukCurrency = currencies.removeValueForKey("UK")

You should use the Dictionary key lookup to retrieve the value of "UK" from the dictionary.

let ukCurrency = currencies["UK"]
