如何给出一个固定的 position 视图，使其不受 SwiftUI 中的滚动影响

Question

Is there a way in SwiftUI to give any view object a fixed position so that it doesn't move when the rest of the view scrolls?

Answer 1

      VStack.init {
            VStack.init(alignment: .center, spacing: 0, content: {
                Text("UnScrollable")
            }).padding()
            
            ScrollView.init {
                VStack {
                    Text("Scrollable")
                }
            }
        }

you'll need to set your frame on the first VStack because if vstack somehow needed more space than current height resolution your scrollview wont visible to the screen.

if you need fixed position like floating button for example you need to use this logic ZStack -> VStack/View With position -> ScrollView you'll need button with custom position for make this to happen,

var body: some View {
    GeometryReader.init { reader in
        ZStack {
            
            ScrollView.init {
                VStack {
                    Text.init("Hello?")
                    Rectangle.init().foregroundColor(.orange).frame(width: reader.size.width, height: 1024, alignment: .center)
                }
            }
            
            VStack.init {
                Text("wakwkakwkaw").position(.init(x: reader.size.width - 100, y: reader.size.height - 100))
            }
        }
    }
}
