You have to assign the value of "UK" which is "Pound" to a constant named ukCurrency.

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

let ukCurrency = currencies["UK"] // I accessed the dictionary by calling "currencies which is the name of the dictionary. Then to get the value of "Pound" you have to call its key. Hope this helps.. Good luck with Swift!
