Please check this exercise. I cannot find the error.

I try it at the Playground, and it looks ok.

dictionaries.swift 
var currencies = [      "US": "Dollar",
                        "UK": "Pound",
                        "JP": "Yen"]

You have assigned the dictionary to a variable, but the challenge asks to assign it to a constant.

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

let ukCurrency = currencies["UK"]
