Hi Sadik,

What you need to do here is create a new constant called ukCurrency and set it's value by retrieving the item from the currencies dictionary that has the key UK.

Here's an example of a similar task that uses pet names.
Apply the same principle show here to answer the code challenge.

let petNames = ["Cat": "Sylvester", "Dog": "Milo", "Rabbit": "Bugs Bunny"]

// Create a new constant called dogName and set it's value by retrieving the 
// item from the petNames dictionary with the key 'Dog'
let dogName = petNames["Dog"]

Hi Sadik,

Make sure that you are retrieving the value from the currencies dictionary.

currencies["UK"]
