how do i assign the value from the currencies dictionary that matches "UK" to the constant ukCurrencies?

trouble getting this question right even though i ran the code successfully in Xcode

dictionaries.swift 
let currencies = ["US": "Dollar", 
                "UK": "Pound", 
                "JP": "Yen"]
 //currencies.removeValueOfKey("UK")
let ukCurrencies = currencies["UK"]


 //let ukCurrency = currencies.removeValueForKey("UK")

let currencies = ["US": "Dollar", "UK": "Pound", "JP": "Yen"] 
let ukCurrency = currencies["UK"]

I think the challenge wants you to use the constant ukCurrency instead of ukCurrencies
