ProgressiveBlurView from My top 3 design “Kisses” I like to add to every app

ProgressiveBlurView.swift

func makeUIView(context: Context) -> UIVisualEffectView {
    let view = UIVisualEffectView(effect: UIBlurEffect(style: .light))
    let filter = (NSClassFromString("CAFilter") as! NSObject.Type)
        .perform(NSSelectorFromString("filterWithType:"), with: "variableBlur")!
        .takeUnretainedValue() as! NSObject

    filter.setValue(20, forKey: "inputRadius")
    view.subviews.first?.layer.filters = [filter]
    return view
}
