I am running the boiler plate App created by Xcode using SwiftData and I am trying to support iPhone and iPad in the same view. I have NavigationSplitView with a List and inside that is a forEach with a .onDelete(perform:). Problem is when I delete the last item in the SwiftData database and tap done on the edit button the app crashes. Here is the view code:
import SwiftUI
import SwiftData
struct ContentView: View {
@Environment(\.modelContext) private var modelContext
@Query private var items: [Item]
var body: some View {
NavigationSplitView {
List {
ForEach(items) { item in
NavigationLink {
Text("Item at \(item.timestamp, format: Date.FormatStyle(date: .numeric, time: .standard))")
} label: {
Text(item.timestamp, format: Date.FormatStyle(date: .numeric, time: .standard))
}
}
.onDelete(perform: deleteItems)
}
.toolbar {
ToolbarItem(placement: .navigationBarTrailing) {
EditButton()
}
ToolbarItem {
Button(action: addItem) {
Label("Add Item", systemImage: "plus")
}
}
}
} detail: {
Text("Select an item")
}
}
private func addItem() {
withAnimation {
let newItem = Item(timestamp: Date())
modelContext.insert(newItem)
}
}
private func deleteItems(offsets: IndexSet) {
withAnimation {
for index in offsets {
modelContext.delete(items[index])
do {
try modelContext.save()
} catch {
print(error)
}
}
}
}
}
#Preview {
ContentView()
.modelContainer(for: Item.self, inMemory: true)
}
The error is "Attempted to modify the selection of an item in an out-of-bounds section"
Using Xcode 15.4
Any help would be much appreciated!
