Hello There,
How can I change the label for onDelete in SwiftUI to e. g. "Löschen"?
Here is my code (just a little bit of ContentView):
struct TodoListView: View {
@State var textValue = ""
@State var descriptionValue = ""
@State var showAddTaskView: Bool = false
@Environment(\.managedObjectContext) private var viewContext
@FetchRequest(sortDescriptors: [NSSortDescriptor(keyPath: \Task.date, ascending: false)])
private var tasks: FetchedResultsTask
var body: some View {
NavigationView {
List() {
ForEach(tasks) { task in
NavigationLink(destination: List { Text(task.beschreibung ?? "Kein Inhalt") }
) {
if (task.title == "Unbenannt") {
Text(task.title ?? "Unbenannt").italic()
} else {
Text(task.title ?? "Unbenannt")
}
}
}.onDelete(perform: deleteTasks)
}
.listStyle(GroupedListStyle())
.navigationTitle("Todo-Liste")
.navigationBarItems( trailing: Button(action: {
showAddTaskView.toggle()
}, label: {
Image(systemName: "plus")
.padding(.leading, 40)
.padding(.bottom, 20)
//.background(Color.yellow)
})
)}
.sheet(isPresented: $showAddTaskView, content: {
NavigationView {
List {
TextField("Aufgaben-Name",
text: $textValue)
TextEditor(text: $descriptionValue)
.padding()
}.navigationTitle("Aufgabe")
.navigationBarItems(leading: Button(action: {
showAddTaskView.toggle()
textValue = ""
descriptionValue = " "
}, label: {
Text("Abbrechen").fontWeight(.regular)
}),trailing: Button(action: {
addTask()
showAddTaskView.toggle()
}, label: {
Text("Hinzufügen")
}))
}
})
}
private func saveContext() {
do {
try viewContext.save()
} catch {
let error = error as NSError
fatalError("Unresolved Error \(error)")
}
}
private func deleteTasks(offsets: IndexSet) {
withAnimation {
offsets.map { tasks[$0] }.forEach(viewContext.delete)
saveContext()
}
}
private func addTask() {
withAnimation {
let newTask = Task(context: viewContext)
if (textValue != "") {
newTask.title = textValue
} else {
newTask.title = "Unbenannt"
}
if (descriptionValue != "") {
newTask.beschreibung = descriptionValue
} else {
newTask.beschreibung = "Kein Inhalt"
}
newTask.date = Date()
textValue = ""
descriptionValue = " "
saveContext()
}
}
}
Thank you for answers.

There is this command/menu bar on iPad since iPadOS 15, which appears, when I long press the cmd key.
How can I disable this, during i am in a texteditor field?
