the task states: Assign the value for key "UK" to a constant named ukCurrency.

you arent changing the dictionary at all, you are just accessing one of the values it stores using a key, and assigning that value to another constant

let currencies = ["US":"Dollar", "UK":"Pound", "JP": "Yen"]
let ukCurrency = currencies["UK"] //= the value of currencies["UK"] which is "Pound"

Woops, actually in swift semicolons are optional unless you want multiple statements on one line. didnt mean to put them in there, it should work without them. edited my answer.
