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

Not sure what I am doing wrong clearly need a lot more practice with this section.

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

They want you to create a new constant named "ukCurrency" and then set it to equal the value of key named "UK":

  1. let ukCurrency
  2. = currencies["UK"]
