Immutable constant assigning key "UK"

the quiz is asking me to assign a key called "UK" in a constant called "currencies" so I used removeValueForKey to retrieve the key and it puts an error in the console saying "removeValueForKey is a mutable only ability" and i do not know what else to use. Help!

Hello Lundwing.

If I got it right you are in the 2/2 task of the dictionary part.

I had to go back to the challenge as I could not understand the task precisely through your description, but here is a hint. You do not need to edit the Dictionary here. They just want you to create a new constant called ukCurrency (let ukCurrency). Then we need to place what is stored in the dictionary currencies that has the key "UK" in there, so:

let ukCurrency = currencies["UK"]
