A lightweight library that can easily blur the view

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        view.bk.addBlur(blurRadius: 0)

        UIView.animate(withDuration: 5) {
            self.view.bk.blurRadius = 5
        }
    }
}

label.bk.addBlur(blurRadius: 3, colorTint: .white, colorTintAlpha: 0.4)
imageView.bk.addBlur(blurRadius: 4, colorTint: .white, colorTintAlpha: 0.2)
view.bk.removeBlur()
view.bk.isBlurHidden = true // or false
