Challenge Task 2 of 2

I have approached this challenge 2 different ways, and both get error messages:

let currencies = [ "US": "Dollar", "UK": "Pound", "JP": "Yen"] let ukCurrency = countries.removeValueForKey("UK")

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

Can anyone help?

Thanks in advance!

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