import SwiftUI struct ContentView: View { @State private var selection = 1 var body: some View { TabView(selection: $selection) { Tab("1", systemImage: "1.circle", value: 1) { Text("Tab 1") } Tab("2", systemImage: "2.circle", value: 2) { Text("Tab 2") } } .tabViewBottomAccessory { if selection == 1 { Text("Bottom Bar for Tab 1") } } } } With this structure, I'm supposing when I select tab 2, the bottom accessory will be hidden, but it is not hidden for the first time, after I click back to tab 1, then click tab 2, it is hidden. I think this is a bug?
