I was coding a sidebar on macOS and folded it with my mouse, but every time I run the app, I can't see the sidebar, so I can't use the sidebar.
If you add a new image once, you can't see the same, but the third window also shows the sidebar well. I don't know why
It's similar when you run it on another computer at all.
Current code
import CoreData
struct ContentView: View {
@Environment(\.managedObjectContext) private var viewContext
@State private var isSidebarVisible: Bool = true
var body: some View {
NavigationView {
if isSidebarVisible {
Sidebar()
}
MemoListView().environment(\.managedObjectContext, viewContext)
}
.frame(minWidth: 700, minHeight: 400)
.toolbar {
ToolbarItem(placement: .navigation) {
Button(action: toggleSidebar) {
Image(systemName: "sidebar.leading")
}
}
}
}
private func toggleSidebar() {
withAnimation {
isSidebarVisible.toggle()
}
}
struct Sidebar: View {
@Environment(\.managedObjectContext) private var viewContext
var body: some View {
List {
NavigationLink(destination: EasyWebListView().environment(\.managedObjectContext, viewContext)) {
Label("Web Links", systemImage: "link")
}
NavigationLink(destination: MemoListView().environment(\.managedObjectContext, viewContext)) {
Label("Memos", systemImage: "note.text")
}
NavigationLink(destination: ThemeListView().environment(\.managedObjectContext, viewContext)) {
Label("Themes", systemImage: "photo.on.rectangle.angled")
}
NavigationLink(destination: AccessView().environment(\.managedObjectContext, viewContext)) {
Label("Access Records", systemImage: "clock.fill")
}
}
.navigationTitle("My App")
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView().environment(\.managedObjectContext, PersistenceController.preview.container.viewContext)
}
}
And the code used when there was a problem before.
import CoreData
struct ContentView: View {
@Environment(\.managedObjectContext) private var viewContext
@State private var isSidebarVisible: Bool = true
var body: some View {
NavigationView {
Sidebar().environment(\.managedObjectContext, viewContext)
MemoListView().environment(\.managedObjectContext, viewContext)
}
.frame(minWidth: 700, minHeight: 400)
.toolbar {
ToolbarItem(placement: .navigation) {
Button(action: {
withAnimation {
isSidebarVisible.toggle()
}
}) {
Image(systemName: "sidebar.leading")
}
}
}
}
struct Sidebar: View {
@Environment(\.managedObjectContext) private var viewContext
var body: some View {
List {
NavigationLink(destination: EasyWebListView().environment(\.managedObjectContext, viewContext)) {
Label("Web Links", systemImage: "link")
}
NavigationLink(destination: MemoListView().environment(\.managedObjectContext, viewContext)) {
Label("Memos", systemImage: "note.text")
}
NavigationLink(destination: ThemeListView().environment(\.managedObjectContext, viewContext)) {
Label("Themes", systemImage: "photo.on.rectangle.angled")
}
NavigationLink(destination: AccessView().environment(\.managedObjectContext, viewContext)) {
Label("Access Records", systemImage: "clock.fill")
}
}
.listStyle(SidebarListStyle())
.navigationTitle("My App")
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView().environment(\.managedObjectContext, PersistenceController.preview.container.viewContext)
}
}
