SwiftUI's tabViewBottomAccessory API Cannot Control Visibility in iOS 26.1

In iOS 26.1, SwiftUI's tabViewBottomAccessory API cannot control visibility properly. The tabViewBottomAccessory remains always visible, which is inconsistent with the behavior in iOS 26.0 / iOS 26.0.1.

` struct ContentView: View {

enum Tabs { case first }

@State private var selection: Tabs = .first @State private var showBottomAccessory: Bool = true

var body: some View { tabView }

var tabView: some View { TabView(selection: $selection) { Tab(value: .first) { content } label: { VStack { Text("first") } } } .tabViewBottomAccessory { if showBottomAccessory { Text("BottomAccessory") } } }

var content: some View { Button("change") { showBottomAccessory.toggle() } } } `
