Метод Swizzling не вызывает оригинальных Touchesbegan и Touchesdended Methods в Swift ⇐ IOS

[Anonymous]

Я пытаюсь реализовать метод, прописываемый в перехват Touchesbegan и Toucheseded, во всех экземплярах Uresponder. Тем не менее, я сталкиваюсь с проблемами, когда исходные методы внутри UiviewContoller не называются,
Короче говоря,
Свиджированные методы не вызывают оригинал touchesbegan и toucheseded в моем uiviewcontroler uiviewcontroller press
extension UIResponder {
static let swizzleTouchMethods: Void = {
let originalBeganSelector = #selector(touchesBegan(_:with:))
let swizzledBeganSelector = #selector(xxx_touchesBegan(_:with:))

guard let originalBeganMethod = class_getInstanceMethod(UIView.self, originalBeganSelector),
let swizzledBeganMethod = class_getInstanceMethod(UIView.self, swizzledBeganSelector) else {
return
}

method_exchangeImplementations(originalBeganMethod, swizzledBeganMethod)

let originalMovedSelector = #selector(touchesMoved(_:with:))
let swizzledMovedSelector = #selector(xxx_touchesMoved(_:with:))

guard let originalMovedMethod = class_getInstanceMethod(UIView.self, originalMovedSelector),
let swizzledMovedMethod = class_getInstanceMethod(UIView.self, swizzledMovedSelector) else {
return
}

method_exchangeImplementations(originalMovedMethod, swizzledMovedMethod)

let originalEndedSelector = #selector(touchesEnded(_:with:))
let swizzledEndedSelector = #selector(xxx_touchesEnded(_:with:))

guard let originalEndedMethod = class_getInstanceMethod(UIView.self, originalEndedSelector),
let swizzledEndedMethod = class_getInstanceMethod(UIView.self, swizzledEndedSelector) else {
return
}

method_exchangeImplementations(originalEndedMethod, swizzledEndedMethod)
}()

@objc func xxx_touchesBegan(_ touches: Set, with event: UIEvent?) {
if let touch = touches.first {
print("Swizzled touch began at: radius \(touch.majorRadius)")

// Call the original method (which is now swizzled)
