Looking for an iOS Developer for help

I have a small problem I am trying to solve and it’s been 2 hours and unfortunately didn’t do it. so this how it looks:
Simulator Screen Recording - iPhone 13 Pro - 2023-08-14 at 16.38.06

and this is the code:

struct Toolbar: View {
    
    var body: some View {
        TabView {
                VStack {
                    Circle()
                       .foregroundColor(.yellow)
                       .frame(width: 500)
                       .offset(x: -100 ,y:-500)
                }
            .tabItem {
                Label("home 1", systemImage: "house")
            }
            
            VStack {
                    Circle()
                       .foregroundColor(.yellow)
                       .frame(width: 500)
                       .offset(x: 0 ,y:-500)
                 }
            .tabItem {
                Label("home 2", systemImage: "house")
            }
       }
  
   }
    
}

What I am trying to do is… to add a small animation for the movement of the circle throw views. any idea how can I achieve that ??
