What's wrong with this code?

Simply can't crack this!

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

let ukCurrency = currencies.removeValueForKey("UK")

Just to add, The challenge is to "Assign the value for key "UK" to a constant named ukCurrency."

I cracked it! The correct code was:

let ukCurrency = currencies["UK"]

Lesson for me? Read the question very carefully. (I believe) my original code would have created a constant with the value "UK", but also REMOVED the key value pair from the dictionary. The latter part (removing from dictionary) was not requested in the question.
