In my SwiftUI app, I have a TabBar with 2 items:
a) TabItem1
b) TabItem2

However on the View itself, I created 2 buttons:
a) Button A
b) Button B

Now I need to switch TabBar items, using the buttons on the View. How can I do this ?

*******

Button(action: {
//call tabItem 1
})
{
    Text("TabItem1")
}

Button(action: {
//call tabItem 2
})
{
    Text("TabItem2")
}

****************************

TabView {
      TabView1View()
        .tabItem {
          Text("TabItem1")
        }

      TabView2View()
        .tabItem {
          Text("TabItem2")
        }

Thank you

You may need to access the selection of TabView:

Code Block struct ContentView: View {
    @State var tabSelection: Int = 1
    var body: some View {
        TabView(selection: $tabSelection) {
            TabView1View(tabSelection: $tabSelection)
                .tabItem {
                    Text("TabItem1")
                }
                .tag(0)
            TabView2View(tabSelection: $tabSelection)
                .tabItem {
                    Text("TabItem2")
                }
                .tag(1)
        }
    }
}
struct TabView1View: View {
    @Binding var tabSelection: Int
    
    var body: some View {
        Button(action: {
            //call tabItem 2
            self.tabSelection = 1
        })
        {
            Text("TabItem1")
        }
        
    }
}
struct TabView2View: View {
    @Binding var tabSelection: Int
    
    var body: some View {
        Button(action: {
            //call tabItem 1
            self.tabSelection = 0
        })
        {
            Text("TabItem2")
        }
    }
}
