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.

Answer 1

Used some of the offered questions out there and created my own. I believe is the most efficient when you want to programmatically set up the title of various UIButtons(in my case I am building a quiz)

By randomising my array list and with just a for loop I printing the item at index to the button title

for view in self.viewForButtons.subviews{
        if view.isKindOfClass(UIButton)
        {
            let button : UIButton = view as! UIButton
            button.setTitle("item[i]", forState: .Normal)
        }
    }
