Assign the value for key "UK" to a constant named ukCurrency. I'm not quite sure how to assign the key value "UK"

Could you help me with assigning the key value "UK" to a constant named ukCurrency?

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

Assigning the key value 'UK' means to get the value at 'UK' from currencies and assigning that. You do this by currencies[Key_Name_String].

I hope this helps ^^
