How to recreate the grid (in screenshot) in SwiftUI without breaking navigation? - swiftui

Question

I am trying to recreate a layout similar to the Reminders app. Looking at it makes me think it was built with SwiftUI. I also believe Apple mentioned so in one of the WWDC videos (can't remember which one).
This above screenshot seems to be a List, with a LazyVGrid as the first View inside the List. Tapping on each of the items in the LazyVGrid, such as Today, Scheduled, All and Flagged, navigates to the relevant screen, which means they are all NavigationLinks. Also note that the LazyVGrid has 2 columns.
And then there is another section "My Lists" which has rows which look like regular list rows in a List with style .insetGrouped. Also, every item in this Section is a NavigationItem, and thus comes with the disclosure indicator on the right as usual. Recreating this is trivial, so it has been left out from the MRE.
I am having trouble recreating the first section, which has that LazyVGrid. I faced 3 problems (as mentioned in the image), of which I have been able to solve the first one only. The other two problems remain. I want to know if this MRE can be fixed, or is my entire approach incorrect.
I am including a minimum reproducible example below.
import SwiftUI
#main
struct TestApp: App {
var body: some Scene {
WindowGroup {
RemindersView()
}
}
}
struct RemindersView: View {
private var columns: [GridItem] = [GridItem(.adaptive(minimum: 150))]
private var smartLists: [SmartList] = SmartList.sampleLists
var body: some View {
NavigationView {
List {
Section(header: Text("Using LazyVGrid")) {
grid
}
Section(header: Text("Using HStack")) {
hstack
}
}
.navigationTitle("Store")
}
.preferredColorScheme(.dark)
}
private var grid: some View {
LazyVGrid(columns: columns, spacing: 8) {
ForEach(smartLists) { smartList in
// This use of **ZStack with an EmptyView with opacity 0** is a hack being used to avoid the disclosure indicator on each item in the grid
ZStack(alignment: .leading) {
NavigationLink( destination: SmartListView(list: smartList)) {
EmptyView()
}
.opacity(0)
SmartListView(list: smartList)
}
}
}
.listRowInsets(EdgeInsets())
.listRowBackground(Color.clear)
}
private var hstack: some View {
ScrollView(.horizontal) {
HStack {
ForEach(smartLists) { smartList in
NavigationLink(destination: SmartListView(list: smartList)) {
SmartListView(list: smartList)
}
.buttonStyle(.plain)
}
}
}
.listRowInsets(EdgeInsets())
.listRowBackground(Color.clear)
}
}
struct RemindersView_Previews: PreviewProvider {
static var previews: some View {
RemindersView()
}
}
struct SmartList: Identifiable {
var id: UUID = UUID()
var title: String
var count: Int
var icon: String
var iconColor: Color
static var sampleLists: [SmartList] {
let today = SmartList(title: "Today", count: 5, icon: "20.circle.fill", iconColor: .blue)
let scheduled = SmartList(title: "Scheduled", count: 12, icon: "calendar.circle.fill", iconColor: .red)
let all = SmartList(title: "All", count: 77, icon: "tray.circle.fill", iconColor: .gray)
let flagged = SmartList(title: "Flagged", count: 5, icon: "flag.circle.fill", iconColor: .orange)
return [today, scheduled, all, flagged]
}
}
struct SmartListView: View {
var list: SmartList
var body: some View {
VStack(alignment: .leading, spacing: 8) {
HStack(alignment: .center) {
Image(systemName: list.icon)
.renderingMode(.original)
.font(.title)
.foregroundColor(list.iconColor)
Spacer()
Text("\(list.count)")
.font(.system(.title, design: .rounded))
.fontWeight(.bold)
.padding(.horizontal, 8)
}
Text(list.title)
.font(.system(.headline, design: .rounded))
.foregroundColor(.secondary)
}
.padding(8)
.background(
RoundedRectangle(cornerRadius: 12)
.foregroundColor(.gray.opacity(0.25))
)
.padding(2)
.frame(minWidth: 150)
}
}
