Hi everyone,
I’m working on a Compose Multiplatform app using Navigation3 on iOS.
In my app, the user can choose the language at runtime.
When an RTL language is selected, I inject LocalLayoutDirection above my NavDisplay, for example:

CompositionLocalProvider(
    LocalLayoutDirection provides if (isRtl) LayoutDirection.Rtl else LayoutDirection.Ltr
) {
    NavDisplay(...)
}

This works for most of the Compose UI.
However, on iOS, the interactive back gesture still starts from the left edge, even when the app is in RTL.
What I would expect in RTL is the opposite of LTR: the back gesture should start from the right edge.

So my questions are:
1. Is there a supported way to make the iOS back gesture respect a runtime RTL language selected inside the app, rather than the system/UIWindow layout direction?
2. Is there a Navigation3-level configuration to control the back gesture edge on iOS?
3. Also, why do the default Navigation3 transition specs use:
AnimatedContentTransitionScope.SlideDirection.Left / Right
instead of:
AnimatedContentTransitionScope.SlideDirection.Start / End
?

Using Start / End would seem more natural for RTL-aware navigation transitions, and this would be handled standardly instead of providing custom transitions on iOS.
Thanks!

The resources localization are already successfully reloaded. The only pain point is the back/transition management 😞

I found a way by applying the layout direction at the root of the SwiftUI application

ContentView()
        .id(isRtl)
        .environment(\.layoutDirection, isRtl ? .rightToLeft : .leftToRight)
