There is no way to change a constant dictionary but the system wants me to?

This is in swift

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

You are not supposed to change the content of the dictionary, the challenges asks you to retrieve the value corresponds to the "UK" key from the dictionary then assign it to the ukCurrency constant.

let ukCurrency = currencies["UK"]
