iOS Swift Basics (retired) Collections What is a Dictionary?

Is something wrong with my syntax?

The objective is to assign a constant 'ukCurrency' value of key 'UK'.

I am doing the following this way: let ukCurrency = ["UK"]

Upon checking this, it is saying that "you code cannot be compiled. Please see the Preview for compile errors" but when I'm clicking Preview, it;s not showing me any error there.

What is the problem then?

1 Answer

You need to reference the dictionary:

let ukCurrency = currencies["UK"]

Hope that helps!


Thanks ya, dude. I figured it out just few minutes before your answer!

Glad you got it sorted!
