Can you explain how to create a custom TabBar View using SwiftUI and incorporate it with a nested NavigationView?

Sure! Here are the steps to create a custom TabBar View using SwiftUI and incorporate it with a nested NavigationView:

Step 1: Create a new SwiftUI View representing your custom TabBar View.

struct CustomTabBarView: View {
    var body: some View {
        // your custom TabBar implementation
    }
}

Step 2: Create a new SwiftUI View representing your root View. This View should contain a NavigationView and your custom TabBar View.

struct RootView: View {
    var body: some View {
        NavigationView {
            // your main content

            // Add your custom TabBar View as a tabBarItems
            .navigationBarItems(
                leading:
                    CustomTabBarView()
                        .frame(width: 150, height: 30, alignment: .leading)
            )
        }
    }
}

Step 3: Configure your custom TabBar View with different buttons that navigate to different View destinations. For example:

struct CustomTabBarView: View {
    var body: some View {
        HStack {
            Button(action: {
                // Navigate to first destination View
            }) {
                Text("First")
            }
            Spacer()
            Button(action: {
                // Navigate to second destination View
            }) {
                Text("Second")
            }
            Spacer()
            Button(action: {
                // Navigate to third destination View
            }) {
                Text("Third")
            }
        }
    }
}

Step 4: Within your main content, use the NavigationLink to navigate to the correct View destination when a TabBar button is tapped. For example:

struct ContentView: View {
    var body: some View {
        List {
            // List content here
        }
        .navigationTitle("Example")
        .navigationBarTitleDisplayMode(.inline)
        .navigationViewStyle(DefaultNavigationViewStyle())
        // use NavigationLinks to navigate when Button from your customTabBar is tapped
        .background(
            NavigationLink(destination: FirstView()) {
                EmptyView()
            }.frame(width: 0, height: 0)
        )
        .background(
            NavigationLink(destination: SecondView()) {
                EmptyView()
            }.frame(width: 0, height: 0)
        )
        .background(
            NavigationLink(destination: ThirdView()) {
                EmptyView()
            }.frame(width: 0, height: 0)
        )
    }
}

That's it! You have now created a custom TabBar View using SwiftUI and incorporated it with a nested NavigationView.
