How do I assign a value of a key which already exists to a new constant?

The key is "UK" and the constant it is assigned to is "currencies". The new constant I need to assign it to is called "ukCurrency.

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

let ukCurrency = 
  ["UK"]
