Not to sure what I am doing wrong here. Please help Question 2 of 2.

I dont get question 2 of 2 on this. Can I reassign a Constant? Im not sure what im doing.

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

currencies["UK"] = "ukCurrency"

The second line of code needs to say

let ukCurrency = "Pound"

let me know if this helps :)

Hi

You can only reassign a value to a variable, not a constant.

I would suggest creating a new constant ukcurrency and assigning that the "UK" key so it takes the value of "pound" from currency dictionary
