Cannot find 'self' in scope; did you mean to use it in a type or extension context? I was programing notifications for my app and this error came up can anyone help me?

import SwiftUI
import UserNotificationsUI
import UserNotifications

struct Notification: View {
    var body: some View {
        Text("Hello, World!")
    }
}

func chekForPermission() {
    let notificaionCenter = UNUserNotificationCenter.current()
    notificaionCenter.getNotificationSettings { settings in
        switch settings.authorizationStatus {
        case .authorized:
            self.dispatchNotification()
        case .denied:
            return
        case .notDetermined:
            notificaionCenter.requestAuthorization(options: [.alert, .sound]) { didAllow, error in
                if didAllow {
                    self.dispatchNotification()
                }
            }
            default:
                return
        }
    }
}

func dispatchNotification() {

struct Notification_Previews: PreviewProvider {
