You would use the string identifier:

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

Thanks Mikael. The video didn't explain it well and I had been trying for a while, so that is why I turned to the forums. Thanks again!

Hi Anish Nuni,

I recommend you next time you have a question about the quizzes that you should go back to the last video you have watched and there you will find the answer to the quiz.

It will save you some expensive time ! :)

Good luck,

Emmanuel.
