How to get a GeometryReader to work only in one dimension? - swiftui

Question

I am using a Geometry Reader to control the horizontal layout of some child views in a HStack. The child views must finally be equally spaced and their numbers are not fixed. This works fine without any problems.
However, the vertical layout, which is solely determined by the content (child views), is expanded to max available height by the geometry reader (which is standard behaviour).
Any suggestions on how to overcome this behaviour are welcome?
(Another way of explaining the problem is to say that a Horizontal Geometry Reader would solve the problem)
Hereby a code snippet added for clarity:
public struct ToolbarView: View {
#ObservedObject public var viewModel: ToolbarViewModel
public var body: some View
{
GeometryReader { geometry in
HStack(spacing:0) {
ForEach(self.viewModel.items.filter({ $0.visible })) { item in
ToolbarItemView(itemViewModel:item, toolbarViewModel: self.viewModel)
.frame(width:geometry.size.width / CGFloat(Double(self.viewModel.items.count)))
.font(self.viewModel.textFont)
}
}
}.frame(height:CGFloat(50))
}
}

As you note in the comments, Spacers will fix this without a GR. You just need to put them in an HStack:
HStack(spacing:0) {
ForEach(self.viewModel.items.filter({ $0.visible })) { item in
HStack {
Spacer()
ToolbarItemView(itemViewModel:item, toolbarViewModel: self.viewModel)
.font(self.viewModel.textFont)
Spacer()
}
}.frame(height:CGFloat(50))
}
