The instruction to "assign the value for key "UK" to a constant named ukCurrency" is just a fancy way of saying "create a constant named ukCurrency and assign it the string "Pound".

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

// Assign the value for key "UK" to a constant named ukCurrency.

let ukCurrency = currencies["UK"]
