Dictionary Challenge iOS Swift

Don't know how to complete the challenge. Though that the following codes were the answer, can't figure it out more:

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

use brackets to retrieve a value from a dictionary using a key like so: dictionaryName["key"], not parenthesis

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