549 PointsHow do you put the value from "UK": "Pound" into a constant named ukCurrency using the removeValueForKey command?
I am on the second objective of what is a dictionary.
//We wil be creating a dicitonary with various country names and there
//country codes
let currencies = ["US": "Dollar", "UK": "Pound", "JP": "Yen"]
let ukCurrency = currencies.removeValueForKey("UK")

Your question seems unrelated to the challenge you've linked it to. If your issue is that you can't get beyond the challenge, then the question is not asking you to remove the element. The question is Assign the value for key "UK" to a constant named ukCurrency; so that just looks like:
let currencies = ["US" : "Dollar", "UK" : "Pound", "JP" : "Yen"]
let ukCurrency = currencies["UK"]
Steve.

let ukCurrency = currencies["UK"]

549 PointsIt did work, but why doesn't the removeValueForKey command work?

Treehouse Moderator 37,862 PointsBecause it's a constant verses a variable you can't change it's content after it's been created.
