Hi there, I don't understand how to assign the value for key "UK" to a constant named ukCurrency.

The first part is correct:

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

However I put;

let ukCurrency = currencies.removeValueForKey("UK")

for the question I am stuck on and it is incorrect. I don't understand.

Hi Rudy,

You're very close, instead of removing the key UK from the array they're simply asking for you to assign it to the constant ukCurrency.

let ukCurrency = currencies["UK"]
