bounds.height//高さ
bounds.width //幅

もう一つの方法

swift

var body: some View {
        GeometryReader { geometry in
            HStack(spacing: 0) {
                Text("Left")
                    .frame(width: geometry.size.width / 2, height: 50)
                    .background(Color.green)
                Text("Right")
                    .frame(width: geometry.size.width / 2, height: 50)
                    .background(Color.blue)
                }
        }
