Why is there a Gap between VStacks in SwiftUI?

Question

A whiteness is seen in the area drawn with the red line. If I change the background color of the most inclusive Vstack, that white area changes.

Deleting spacer() lines doesn't work.

Why is there a gap even though there is no space in between?

struct TabbarView: View {    
var body: some View {        
    VStack{
        Spacer()   
            ZStack{
                Color.orange.opacity(0.5)
                VStack(spacing: 0){
                    Text("Home")
                        .padding()
                }
            }            
        Spacer()            
        HStack{
            VStack{
                Image(systemName: "homekit")
                    .resizable()
                    .aspectRatio(contentMode: .fit)
                    .frame(width: UIScreen.main.bounds.size.width / 15, height: UIScreen.main.bounds.size.height / 25)
            }
        }
        .frame(width: UIScreen.main.bounds.size.width, height: UIScreen.main.bounds.size.height / 13)
        .background(Color.purple)            
    }
    .ignoresSafeArea()      
   // .background(Color.purple.shadow(radius: 2))
}

}

FYI, that is still not an MRE. You need to post the `HomeView` which, at least, is the view that is not working. When you post the code, you should be able to take it, as is, copy and run it. As deleting the two `Spacer()` doesn't solve the problem, the problem could be in the actual views not shown, just referred to. — Yrb, Apr 26 '22 at 19:08
I fixed the code and image in its simplest form. I apologize for using wrongly. — Alican Kurt, Apr 27 '22 at 05:47

you can add for VStack:

 VStack {}
            .frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity, alignment: .center)

updated:

struct ContentView: View {
    var body: some View {
        ZStack {
            Color.orange.opacity(0.5)
            VStack {
                Spacer()
                VStack(spacing: 0){
                    Text("Home")
                        .padding()
                }
                Spacer()
                HStack {
                    VStack {
                        Image(systemName: "homekit")
                            .resizable()
                            .aspectRatio(contentMode: .fit)
                            .frame(width: 25, height: 25, alignment: .center)
                            .frame(width: UIScreen.main.bounds.size.width / 15, height: UIScreen.main.bounds.size.height / 25)
                    }
                }
                .frame(width: UIScreen.main.bounds.size.width, height: UIScreen.main.bounds.size.height / 13)
                .background(Color.purple)
            }
            
        }
        .ignoresSafeArea()
        .frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity)
    }
}

you used nesting incorrectly and there is a native TabView for tabs

result:
