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.

This code seems to be quite useful for iterating over any object within a view, just change UIButton for any other subview type such as UIView or UIImageView, etc.

let filteredSubviews = self.view.subviews.filter({
    $0.isKindOfClass(UIButton)})

for view in filteredSubviews {
    //Do something        
}
