UIView extension to easily add and remove a blur (UIVisualEffectView)

UIView+Extension.swift

import UIKit

extension UIView {
  func blurView(style: UIBlurEffect.Style) {
    var blurEffectView = UIVisualEffectView()
    let blurEffect = UIBlurEffect(style: style)
    blurEffectView = UIVisualEffectView(effect: blurEffect)
    blurEffectView.frame = bounds
    addSubview(blurEffectView)
  }
  
  func removeBlur() {
    for view in self.subviews {
      if let view = view as? UIVisualEffectView {
        view.removeFromSuperview()
      }
    }
  }
}

@hp0101 I've updated for Swift 4.2.

Thanks!

I replaced "self.subviews" with "view.subviews"
