How to add a UIButton to Swift Playground?

Question

So I opened up playground, I just want to add a simple UIButton (or a simple UIView) for testing purposes. I can't get it to display though. This is what I have so far:

import UIKit

var uiButton    = UIButton.buttonWithType(UIButtonType.System) as UIButton
uiButton.frame  = CGRectMake(0, 0, 100, 100)
uiButton.setTitle("Test", forState: UIControlState.Normal);
//self.view.addSubview(uiButton) <-- doesn't work

Do you guys know what I'm doing wrong? Thanks

I think you can add button into playground and your code is correct you can see your button here when you click on Quick Look:

or you can see that button with clicking on Value History:

you dont need to add that into view.
