I've created a constant named ukCurrency, and used the UK key to access it, but it still says I'm doing something wrong.

I might just be doing the wrong steps

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

Hey Austin,

I saw a post a few days ago as to not have the value removed, Have you tried this?

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

let ukCurrency = currencies["UK"]
