Blur effect on view background

Question

I have this extension, and I was hoping for a blur background, where I can see blur through the view:

import Foundation
import UIKit

extension UIView
{
    func addBlurEffect()
    {
        if !UIAccessibilityIsReduceTransparencyEnabled() {
            self.backgroundColor = UIColor.clear

            let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.light)
            let blurEffectView = UIVisualEffectView(effect: blurEffect)
            blurEffectView.frame = self.bounds
            blurEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
            self.addSubview(blurEffectView)
        } else {
            self.backgroundColor = UIColor.white
        }

    }
}

Then I use it like this:

let v = UIView(frame: self.view.frame)

v.addBlurEffect()


self.view.addSubview(v)

But I can not see anything under the view?

Add this framework to your project.

Add transparent view over your background and setup blur (view Readme on github) Preview
