Magnification gesture to scale ScrollView's content.

Hello!

I am trying out new SwiftUI and I have to say that I love it, but I've got some problems implementing few features.
First issue is that I am not sure how can I scale content of ScrollView, to make content of that View smaller, but there would be more subviews visible.

Here's my code:

Code Block swift
	@State private var scale: CGFloat = 1.0
	var body: some View {
		ScrollView([.horizontal]) {
			HStack(alignment: .top) {
				ForEach(0..<5, id: \.self) { _ in
					ScrollView(.vertical) {
						LazyVGrid(columns: [GridItem(.fixed(300), spacing: 10)], spacing: 10) {
							ForEach(0..<5, id: \.self) { _ in
								Rectangle()
									.frame(width: 300, height: 300, alignment: .center)
							}
						}
					}
					.padding(.leading, 10)
				}
			}
			.scaleEffect(scale)
		}
		.gesture(
			MagnificationGesture()
				.onChanged { value  in
					scale = value.magnitude
				})
	}
}

If You paste that code to a project, You will see that app scales whole ScrollView, not its content.

And when we're talking about gestures, I would really appreciate if someone would share here how can I prioritize the gestures.

Thanks for reading!
