Struggling with this one. When I use let ukCurrency = UK, the Xcode program will run it fine, but tutorial says no go.

in the second line you simply assign a value of UK to ukCurrency, but the challenge ask to get the right value of the "UK" key of the currencies array.

this is the right code:

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

let ukCurrency = currencies["UK"]
