Abdullah,

Challenge Task 2 of 2 Its asking you to assign the value for key "UK" to a constant named ukCurrency.

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

The question is: Assign the value for key "UK" to a constant named ukCurrency.

so you need to do the following:

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