NavigationLink inside List applies to HStack instead of each element

Question

I'm trying to follow Composing Complex Interfaces guide on SwiftUI and having issues getting NavigationLink to work properly on iOS 13 beta 3 and now beta 4.

If you just download the project files and try running it, click on any of the Lake images - nothing will happen. However if you click on the header "Lakes" it'll start opening every single lake one after another which is not a behaviour anyone would expect.

Seems like NavigationLink is broken in "complex" interfaces. Is there a workaround?

I've tried making it less complex and removing HStack of List helps to get NavigationLinks somewhat to work but then I can't build the full interface like in example.

Relevant parts of the code:

    var body: some View {
        NavigationView {
            List {
                FeaturedLandmarks(landmarks: featured)
                    .scaledToFill()
                    .frame(height: 200)
                    .clipped()
                    .listRowInsets(EdgeInsets())

                ForEach(categories.keys.sorted(), id: \.self) { key in
                    CategoryRow(categoryName: key, items: self.categories[key]!)
                }
                .listRowInsets(EdgeInsets())

                NavigationLink(destination: LandmarkList()) {
                    Text("See All")
                }
            }
            .navigationBarTitle(Text("Featured"))
            .navigationBarItems(trailing: profileButton)
            .sheet(isPresented: $showingProfile) {
                ProfileHost()
            }
        }
    }


struct CategoryRow: View {
    var categoryName: String
    var items: [Landmark]

    var body: some View {
        VStack(alignment: .leading) {
            Text(self.categoryName)
                .font(.headline)
                .padding(.leading, 15)
                .padding(.top, 5)

            ScrollView(.horizontal, showsIndicators: false) {
                HStack(alignment: .top, spacing: 0) {
                    ForEach(self.items, id: \.name) { landmark in
                        NavigationLink(
                            destination: LandmarkDetail(
                                landmark: landmark
                            )
                        ) {
                            CategoryItem(landmark: landmark)
                        }
                    }
                }
            }
            .frame(height: 185)
        }
    }
}

struct CategoryItem: View {
    var landmark: Landmark
    var body: some View {
        VStack(alignment: .leading) {
            landmark
                .image(forSize: 155)
                .renderingMode(.original)
                .cornerRadius(5)
            Text(landmark.name)
                .foregroundColor(.primary)
                .font(.caption)
        }
        .padding(.leading, 15)
    }
}

Answer 1

It looks like there is a bug with NavigationLink instances that aren't directly contained in a List. If you replace the outermost List with a ScrollView and a VStack then the inner NavigationLinks work correctly:

i.e.

 var body: some View {
    NavigationView {
        ScrollView(.vertical, showsIndicators: true) {
            VStack {
                FeaturedLandmarks(landmarks: featured)
                    .scaledToFill()
                    .frame(height: 200)
                    .clipped()
                    .listRowInsets(EdgeInsets())

                ForEach(categories.keys.sorted(), id: \.self) { key in
                    CategoryRow(categoryName: key, items: self.categories[key]!)
                }
                .listRowInsets(EdgeInsets())

                NavigationLink(destination: LandmarkList()) {
                    Text("See All")
                }
            }
        }
        .navigationBarTitle(Text("Featured"))
    }
}
