Disable swipe back gesture in Swift

Question

Been looking around on here for a while but can\'t seem to find a working solution.

I\'m trying to disable the swipe to go back to previous view gesture, in Swift.

Answer 1

RowanPD's logic for Swift 4

private var popGesture: UIGestureRecognizer?

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    if navigationController!.responds(to: #selector(getter: UINavigationController.interactivePopGestureRecognizer)) {
        self.popGesture = navigationController!.interactivePopGestureRecognizer
        self.navigationController!.view.removeGestureRecognizer(navigationController!.interactivePopGestureRecognizer!)
    }

}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    if let gesture = self.popGesture {
        self.navigationController!.view.addGestureRecognizer(gesture)
    }

}
