When displaying a view using a navigation Split View as a sheet, the toolbar button will disappear if you leave the app and resume it.
import SwiftUI
struct Folder: Hashable, Identifiable {
let id = UUID()
let name: String
}
struct ContentView: View {
@State private var showingSettings = false
var body: some View {
VStack {
Button {
showingSettings.toggle()
} label: {
Text("Settings")
}
}
.sheet(isPresented: $showingSettings, content: {
SettingsView()
})
.padding()
}
}
struct SettingsView: View {
@Environment(\.dismiss) private var dismiss
@State private var selectedFolder: Folder? = nil
private var folders = [Folder(name: "Recents"), Folder(name: "Deleted"), Folder(name: "Custom")]
var body: some View {
NavigationSplitView {
SidebarView(selectedFolder: $selectedFolder, folders: folders)
} detail: {
VStack {
if let folder = selectedFolder {
Text(folder.name)
}
else {
Text("No selection")
}
}
.toolbar {
ToolbarItem(placement: .cancellationAction) {
Button {
dismiss()
} label: {
Text("Cancel")
}
}
ToolbarItem(placement: .confirmationAction) {
Button {
dismiss()
} label: {
Text("Save")
}
}
}
}
}
}
struct SidebarView: View {
@Binding var selectedFolder: Folder?
var folders: [Folder]
var body: some View {
List(selection: $selectedFolder) {
ForEach(folders) { folder in
NavigationLink(value: folder) {
Text(folder.name)
}
}
}
}
}
Steps to reproduce the issue:
Launch the attached project on an iPad or iPad simulator
Tap the Settings button
Select one item in the sidebar
Use the app switcher to open an other app or just leave the app
Bring back the app
Result:
Both Cancel and Save buttons are gone.
Note:
This will not occur if no item is selected in the sidebar.
