The code I used below is not center centered. the top space is twice as much as the bottom space. Don't need to be equal to the bottom and top space? How I can center Text?
struct ContentView: View {
    
    var body: some View {
        ZStack(alignment:.center) {
            Color.red
            
            Text("onna")
                .font(.system(size: 60))
        }
        .frame(width: 222, height: 60)
    }
}

 
                        
Here a way for you to set the value you want:
