iOS 26 provides a brand new gesture to deal with this case. UINavigationController interactiveContentPopGestureRecognizer will be disabled to forestall swiping from the content material space of the display. This then solely permits swiping from the left fringe of the display.
If you wish to stop content material space swiping for all view controllers within the navigation stack, add the next line to the viewDidAppear of the basis view controller:
navigationController?.interactiveContentPopGestureRecognizer?.isEnabled = false
In the event you solely wish to stop it for a particular view controller within the stack, then disable it within the viewDidAppear of that one view controller and re-enable it in its viewDidDisappear.
Don’t use the viewWillAppear or viewWillDisappear strategies since these are referred to as initially of the interactive swiping even when you find yourself canceling the dismissal.
