ios – How to create a swipe down gesture in swiftUI?

I want to create a swipe down gesture that runs a function when detected.

.gesture(
            DragGesture()
                .onChanged { value in
                    if value.translation.height > 0 && abs(value.translation.height) > abs(value.translation.width) {
                        addTask()
                    }
                }
        )

this is the closest i got but with this implementation it makes the swipeActions attatched to the forEach slow and laggy.
is there a better way ?

let yellowCustom = Color(red: 1, green: 0.811, blue: 0, opacity: 1.0)

struct ContentView: View {
//SwiftData
@Environment(\.modelContext) var modelContext
@Query(sort: [SortDescriptor(\Task.complete), SortDescriptor(\Task.date, order: .reverse)]) var task: [Task]
@State private var path = [Task]()

var body: some View {
    NavigationStack(path: $path) {
        List {
            ForEach(task) { task in
                TasksView(task: task)
                    .strikethrough(task.complete)
                    .foregroundColor(task.complete ? .gray : .primary)
                
                //Done Gesture
                    .swipeActions(edge: .leading) {
                        if task.complete {
                            Button("Not Done") {
                                notDone(task: task)

//Checks if user launched the app before

//Sort Boolean
