I don't know if i'm understanding the question

I tried multiple ways of answering this question, but i'm beginning to think that maybe I don't understand what it is asking me.

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

let ukCurrency = currencies.removeValueForKey("UK")

You have to access to "UK" value, not remove it.

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

let ukCurrency = currencies["UK"]

Have a nice day!
