Need an Example

The quiz asks me to assign a constant to a key value, the video does not do this specifically. with the info provided i want to do this: let ukCurrency = ("UK") Please show me an example. I feel these quizzes are more focus on me asking questions than the actual content.

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

Hello Daniel so the code I think you need is the following

let ukCurrency = currencies["UK"]

so with this line of code we are creating a constant named ukCurrency and we assign a key Value. All we need to do is call up your dictionary and the Key ("UK"). with this we get the value "Pound" assign to your constant. Hope this helps !!
