SwiftUI: Build View from bottom alignment in scrollView

Question

Is there a way to build UI elements in SwiftUI inside scroll view with bottom Alignment?

My use case: I have a screen where the screen has

1. Spacer ( What ever is left after allocating below elements )
2. LogoView
3. Spacer() - 30
4. Some Text - 4/5 lines
5. Spacer() - 50 (this will be calculated off of GR size Height)
6. HStack with Two Button - This should be pinned to bottom of view / ScrollView

I would like to know how Can I pin the HStack view to ScrollView Bottom

I've replicated my setup and reproduced my problems in a Swift playground like so

struct ContentView: View {
        var body: some View {
        GeometryReader { gr in
            ScrollView {
                VStack {
                    Spacer()
                    Image(systemName: "applelogo")
                        .resizable()
                        .frame(width: gr.size.width * 0.5, height: gr.size.height * 0.3, alignment: .center)
                    Spacer().padding(.bottom, gr.size.height * 0.01)
                    Text("SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME")
                        .fontWeight(.regular)
                        .foregroundColor(.green)
                        .multilineTextAlignment(.center)
                        .padding(.top, gr.size.height * 0.05)
                        .padding(.horizontal, 40)
                        .layoutPriority(1)
                    Spacer()
                        .frame(minHeight: gr.size.height * 0.12)
                    HStack {
                        Button(action: {

                        }, label: {
                            Text("Button 1")
                        })
                        .foregroundColor(Color.white)
                        .padding(.vertical)
                        .frame(minWidth: 0, maxWidth: .infinity)
                        .background(Color.blue)
                        .cornerRadius(8)

                        Button(action: {

                        }, label: {
                            Text("Button 2")
                        })
                        .foregroundColor(Color.white)
                        .padding(.vertical)
                        .frame(minWidth: 0, maxWidth: .infinity)
                        .background(Color.blue)
                        .cornerRadius(8)
                    }
                    .padding(.horizontal, 20)
                }
                //.frame(maxWidth: .infinity, maxHeight: .infinity)
            }
        }
    }
}

I understand that when scrollView is introduced in SwiftUI view Spacer length is changed to Zero, Would like to know what's the best way to achieve this

struct SampleView: View {
    var body: some View {
        GeometryReader { gr in
            VStack {
                ScrollView {
                    VStack {

                        // Fills whatever space is left
                        Rectangle()
                            .foregroundColor(.clear)

                        Image(systemName: "applelogo")
                            .resizable()
                            .frame(width: gr.size.width * 0.5, height: gr.size.height * 0.3, alignment: .center)
                            .padding(.bottom, gr.size.height * 0.06)


                        Text("SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME TEXT SOME")
                            .fontWeight(.regular)
                            .foregroundColor(.green)
                            .multilineTextAlignment(.center)
                            .padding(.horizontal, 40)
                            .layoutPriority(1)


                        // Fills 12 %
                        Rectangle()
                            .frame(height: gr.size.height * 0.12)
                            .foregroundColor(.clear)

                        HStack {

                            Button(action: {
                            }, label: {
                                Text("Button 1")
                            })
                            .foregroundColor(Color.white)
                            .padding(.vertical)
                            .frame(minWidth: 0, maxWidth: .infinity)
                            .background(Color.blue)
                            .cornerRadius(8)

                            Button(action: {
                            }, label: {
                                Text("Button 2")
                            })
                            .foregroundColor(Color.white)
                            .padding(.vertical)
                            .frame(minWidth: 0, maxWidth: .infinity)
                            .background(Color.blue)
                            .cornerRadius(8)
                        }
                        .padding(.horizontal, 20)
                        .padding(.bottom, 20)

                    }

                    // Makes the content stretch to fill the whole scroll view, but won't be limited (it can grow beyond if needed)
                    .frame(minHeight: gr.size.height)
                }
            }
        }
    }
}

Answer 2

I wanted the scrollview to appear bottom to top instead of top to bottom. This had my answer: https://www.thirdrocktechkno.com/blog/implementing-reversed-scrolling-behaviour-in-swiftui/

TLDR: .rotationEffect(Angle(degrees: 180)).scaleEffect(x: -1.0, y: 1.0, anchor: .center) on the scrollview AND on the items in the scrollview
