How to loop through all UIButtons in my Swift view?

Question

How would I loop through all UIButtons in my view in Swift? I would want to set all the titles to \"\", but my for-loop in Swift is giving an error.

Looping over subview works, but it's sometimes a little ugly, and has other issues.

If you need to loop over some specific buttons, for example to add corner radius or change tint or background color, you can use an array of IBOutlets and then loop over that.

var buttons = [SkipBtn, AllowBtn]
for button in buttons as! [UIButton] {
    button.layer.cornerRadius = 5
}
