I've failed to make a constant named ukCurrency and assigning the value for the key UK using removeValueFor.. Any tips?

Can anyone give any insight on what I'm doing wrong?

It is pretty easy to get the object associated with the key. Do:

Array["key"]

So in this case:

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

let ukCurrency = currencies["UK"]

Thanks for clearing that up. I was trying to create the constant by using currencies.removeValueForKey(“”).
