swift - Hide navigation bar without losing swipe back gesture in SwiftUI

Question

In SwiftUI, whenever the navigation bar is hidden, the swipe to go back gesture is disabled as well.

Is there any way to hide the navigation bar while preserving the swipe back gesture in SwiftUI? I've already had a custom "Back" button, but still need the gesture.

I've seen some solutions for UIKit, but still don't know how to do it in SwiftUI

Here is the code to try yourself:

import SwiftUI

struct RootView: View {
    var body: some View {
        NavigationView {
            NavigationLink(destination: SecondView()) {
                Text("Go to second view")
            }
        }
    }
}

struct SecondView: View {
    var body: some View{
        Text("As you can see, swipe to go back will not work")
        .navigationBarTitle("")
        .navigationBarHidden(true)
    }
}

Any suggestions or solutions are greatly appreciated

This should work by just extending UINavigationController.

extension UINavigationController: UIGestureRecognizerDelegate {
    override open func viewDidLoad() {
        super.viewDidLoad()
        interactivePopGestureRecognizer?.delegate = self
    }

    public func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
        return viewControllers.count > 1
    }
}
