Disable swipe-back for a NavigationLink SwiftUI

Only complete removal of the gesture recognizer worked for me.
I wrapped it up into a single modifier (to be added to the detail view).

struct ContentView: View {
    
    var body: some View {
        VStack {
            ...
        )
        .disableSwipeBack()
    }
}

DisableSwipeBack.swift

import Foundation
import SwiftUI

extension View {
    func disableSwipeBack() -> some View {
        self.background(
            DisableSwipeBackView()
        )
    }
}

struct DisableSwipeBackView: UIViewControllerRepresentable {
    
    typealias UIViewControllerType = DisableSwipeBackViewController
    
    
    func makeUIViewController(context: Context) -> UIViewControllerType {
        UIViewControllerType()
    }
    
    func updateUIViewController(_ uiViewController: UIViewControllerType, context: Context) {
    }
}

class DisableSwipeBackViewController: UIViewController {
    
    override func didMove(toParent parent: UIViewController?) {
        super.didMove(toParent: parent)
        if let parent = parent?.parent,
           let navigationController = parent.navigationController,
           let interactivePopGestureRecognizer = navigationController.interactivePopGestureRecognizer {
            navigationController.view.removeGestureRecognizer(interactivePopGestureRecognizer)
        }
    }
}

You can resolve the navigation controller without third party by using a UIViewControllerRepresentable in the SwiftUI hierarchy, then access the parent of its parent.
