Marco, after reading the instructions for the code challenge, it seems that you accidentally set your dictionary to a variable instead of a constant.

Here is the following code to pass the challenge: 

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

If you have any questions, feel free to ask!

I'd go with:

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

Think you just needed a constant instead of a variable.
