Can somebody explain to me what I am supposed to do here exactly?

"Assign the value for key "UK" to a constant named ukCurrency. "

let ukCurrency = countries.removeValueForKey("UK") is what I was thinking, but apparently not.

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

Hi, Robert, this part of challenge is asking you to retrieve the value associated with the "UK" key from the currencies dictionary; then assign that value to a constant ukCurrency.

let ukCurrency = currencies["UK"]
