Hello :

In your code, you are removing a value. The challenge is asking to assign the value of "UK" in a constant.

When you want to access a value in a dictionary you call the dictionary, and then the key.

dictionary["Key"]

This will return you the value for that key. 

let constant = dictionary["Key"]

And this is declaring a new constant with the value that the dictionary returns from that key.

Good luck
