Remove BlurView in swift

I have a UIView that contains buttons and labels. When these buttons are pressed, this UIView will become blur using the code below.

@IBOutlet weak var blurView: UIView!
var blurEffect = UIBlurEffect(style: UIBlurEffectStyle.Dark)
var blurEffectView = UIVisualEffectView(effect: blurEffect)
blurEffectView.frame = blurView.bounds
blurView.addSubview(blurEffectView)

However, I want to remove the blur effect later on. What is the code for removing the blurred UIView?

It's hard to know exactly what is going on in your code, as you've clearly posted a cut up version (the last 4 lines are part of a method somewhere, presumably).

You could do something like this to remove all UIVisualEffectView subviews from your blurView:

for subview in blurView.subviews {
    if subview is UIVisualEffectView {
        subview.removeFromSuperview()
    }
}
