Can someone help?

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

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

Hey Abdullah, Since you are trying to access the the value of a key in the dictionary "currencies", you must specify that you want to access a key in that dictionary.

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

All I did was change the ["UK"] to currencies["UK"], so your program knows you want to access the key "UK" from your currencies dictionary.
