You don't need to remove the key or value from currencies. You just need to create a constant that only contains the UK value. So you target the value of Pound by using the currencies array and telling it which key you would like to access using UK. Like below...

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