注意：Xcode 11.2/iOS 13.2上出现异常

据我所知，这是一张重新排版的照片，达到了你所要求的效果。
然而，尽管以下代码中没有任何犯罪行为，但在导航返回时，UIKit内部出现异常：

2019-11-24 10:54:36.644037+0200 Test[1180:41920] *** Terminating
app due to  uncaught exception 'NSInternalInconsistencyException',

进近代码

var body: some View {
    NavigationView {
        TabView {
            List(fakeUser) { user in
                NavigationLink(destination: ChatDetailView(user: user)) {
                    ChatCell(user: user)
                }
            }
            .navigationBarTitle("Chats")
            .navigationBarItems(leading: leadingBarItem, trailing: trailingBarItem)
            .tabItem {
                Image(systemName: "message.fill")
                    .font(.system(size: 20))
                Text("Chats")
            }
        }
        .navigationBarTitle("Chats")
    }
}

在iOS 16中，您有此选项：

.toolbar(.hidden, for: .tabBar)

只需将其附加到要推送的视图。
