This is simply constructing the dictionary like the questions asks, then assigning one of the values inside the dictionary to a constant named ukCurrency.

Construct the dictionary like so:

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

Then assign the UK value of the dictionary to the constant ukCurrency:

let ukCurrency = currencies["UK"]
