SwiftUI 转换无法正常工作

Question

I am trying to make a transition from bottom edge to top when a view appears.

 ZStack{
   VStack {
    .
    .//other components
    .
    if self.modalShown {
        HStack {
            GeometryReader { geometry in
                BottomSheetView(
                    isOpen: self.$modalShown,
                    maxHeight: geometry.size.height * 0.6
                ) {
                    ZStack(alignment: .bottom) {
                        FiltersView(hideControl: self.$modalShown)
                            .transition(.move(edge: .bottom))
                    }

                    .edgesIgnoringSafeArea(.bottom)
                }
            }
        }
        .accessibility(identifier: "modalFilterView")
    } 
}

The problem is that when this view appears, it performs a kind of alpha 0 to alpha 1 transition. And when the view is dismissed it does not perform any transition.

Could be related this undesired behavior with the zIndex?

The problem was that the transition modifier was in the wrong place:

 ZStack{
   VStack {
    .
    .//other components
    .
    if self.modalShown {
        HStack {
            GeometryReader { geometry in
                BottomSheetView(
                    isOpen: self.$modalShown,
                    maxHeight: geometry.size.height * 0.6
                ) {
                    ZStack(alignment: .bottom) {
                        FiltersView(hideControl: self.$modalShown)
                    }
                    .edgesIgnoringSafeArea(.bottom)
                }
            }
        }
        .transition(.move(edge: .bottom))
        .accessibility(identifier: "modalFilterView")
    } 
}
