Still an issue on iOS 26.3 Beta 1. FB21364908

FB21365706 It looks like the tabViewBottomAccessory view doesn’t adapt properly when the background isn’t white. Interestingly, the tab bar itself adapts perfectly. struct ContentView: View { enum TabValue: String { case first, second } @State var selectedTab: TabValue = .first var body: some View { TabView(selection: $selectedTab) { Tab("first", systemImage: "1.circle", value: .first) { ScrollView(.vertical) { Spacer(minLength: 800) LinearGradient( colors: [.yellow, .black], startPoint: .top, endPoint: .bottom ) .frame(height: 800) } } Tab("second", systemImage: "2.circle", value: .second) { } } .tabViewBottomAccessory { HStack { Text("Title") Spacer() Image(systemName: "play.fill") } .padding(.horizontal) } } }
