Swipe from left to right to go back

[GaniduAsh]

Trying to implement a custom navigation as the NavigationView that SwiftUI supports doesnt provide many features,

Notice the one in here is quite impressive. But I noticed this doesnt have the feature to go back to the previous screen by dragging left to right (default go back feature that iOS provides)

Is there a way to get it done ?

Hi @GaniduAsh , thanks for asking. Unfortunately, at the moment, there's no easy way to get the "swipe to pop" feature with NavigationStackView. Anyway, it's a very interesting feature to work on.

Yeah i Noticed it. I think the reason is having your own navigation stack as its hard to maintain all the features that default iOS navigation has, hence i used UIViewControllerRepresentable and the stack which comes with UINavigation.

I would like to have that swipe to pop gesture, and would help to implement the same, I am new to SwiftUI coming from Android, but not having this swipe gesture does not feel like iOS to me when implementing this Navigation Stack, apart from that it works smooth and easy to integrate.

But its the default iOS behavior and its a must feature in apple . I would suggest to integrate it as i mentioned earlier

Is there any solution for this case?

@JuanVeGu-Ionix Unfortunately not yet.

To solve this, for the moment, I get the swipe gesture to the right and pass it the pop() method 😬

@JuanVeGu-Ionix but I think this approach is not the same as the default iOS behavior. I mean you cannot swipe the current screen back and forth, right?

Would also love to see this feature!

@JuanVeGu-Ionix It would be great if you showed us how you've implemented this feature. We could find a way to integrate your implementation in this project. Thanks.

It's probably something like this where the pop() method is called in the .right case. But as I said, this does not replicate the iOS gesture which also includes swiping the current screen only partly.

Yes, I created a ViewModifier with the next structured

 struct BackToView: ViewModifier {
     let function: () -> Void
 
     func body(content: Content) -> some View {
         content.gesture(DragGesture(minimumDistance: 20, coordinateSpace: .global).onEnded { value in
             let horizontalAmount = value.translation.width as CGFloat
             let verticalAmount = value.translation.height as CGFloat
              
             if abs(horizontalAmount) > abs(verticalAmount) && horizontalAmount > 0 {
                 function()
             }
         })
     }
 }

I know, it's not the right answer, but it works for me
