Cannot Assign the value for key "UK" to a constant named ukCurrency.

As the title says, I am having trouble assigning the value "UK" to a constant named "ukCurrency". Here are the lines of code I have tried:

currencies["UK"] = "ukCurrency"

and

currencies.removeValueForKey("UK": "ukCurrency)

Thanks in advance!

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

Thanks man! I actually just figured it out from a similar post about five minutes ago. I think I understand it now.

QA;TL stands for "Question Answered, Thread Locked"

It's used a lot on other forums so I assumed y'all would know about it.
