How to put a Header and Footer to the Top and Bottom of a View, respectively

I need the header and footer to stay at the top and bottom of a view, but I can’t get it to work.

The view is this:

Scrollview {
    content
}

content is:

error()
VStack(spacing: 0) {
moreViews()
}

and error is:

VStack(alignment: .center) {
header
   .frame(alignment: .top)
Spacer()
footer
   .frame(alignment: .bottom)
}
.frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .top)
}
