In Chapter 15’s sample code for HNReader, the timer does not fire when the VStack is after the ForEach loop:
ForEach(self.model.stories) { story in
VStack(alignment: .leading, spacing: 10) { …
However, when I switch those lines, the timer will fire normally:
VStack(alignment: .leading, spacing: 10) {
ForEach(self.model.stories) { story in
i.e. ForEach has to be inside the VStack for the timer to fire. I ran the sample code under Xcode 11.4.1
