Hi,

You're nearly there. To create the instance call the Class with the initialiser's parameters:

var rounded = RoundButton(width: 5, height: 5)

That should work.

I copied and pasted this and it says it is wrong.. I think something is glitching because I typed this in prior to looking and when I saw that this was the correct response I wanted to hit my computer for making me so frustrated

What have you got on your screen? If you can post your code, I can have a look to see what's up.
