Remove / cancel pending local notifications from NotificationCenter - ios

Question

I have a view controller that initializes a local scheduled notification on viewDidLoad. I would like to stop this notification from happening if a user presses a button.
I have found some answers saying to use center.removeAllPendingNotificationRequests() but this does not work for NotificationCenter
let notificationPublisher = NotificationPublisher()
override func viewDidLoad() {
notificationPublisher.sendNotification(title: "Test", subtitle: "", body: "Test", badge: nil, delayInterval: Int(breakTime))
}
#objc func buttonPressed() {
// Want to dismiss the pending notification here
}
NotificationPublisher.swift:
import UIKit
import UserNotifications
class NotificationPublisher: NSObject {
let notificationCenter = NotificationCenter.default
func sendNotification(title: String, subtitle: String, body: String, badge: Int?, delayInterval: Int?) {
let notificationContent = UNMutableNotificationContent()
notificationContent.title = title
notificationContent.subtitle = subtitle
notificationContent.body = body
var delayTimeTrigger: UNTimeIntervalNotificationTrigger?
if let delayInterval = delayInterval {
delayTimeTrigger = UNTimeIntervalNotificationTrigger(timeInterval: TimeInterval(delayInterval), repeats: false)
}
if let badge = badge {
var currentBadgeCount = UIApplication.shared.applicationIconBadgeNumber
currentBadgeCount += badge
notificationContent.badge = NSNumber(integerLiteral: currentBadgeCount)
}
notificationContent.sound = UNNotificationSound.default
UNUserNotificationCenter.current().delegate = self
let request = UNNotificationRequest(identifier: "TestLocalNotification", content: notificationContent, trigger: delayTimeTrigger)
UNUserNotificationCenter.current().add(request) { (error) in
if let error = error {
print(error.localizedDescription)
}
}
}
}
extension NotificationPublisher: UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
let identifer = response.actionIdentifier
switch identifer {
case UNNotificationDismissActionIdentifier:
print("The notification was dismissed")
completionHandler()
case UNNotificationDefaultActionIdentifier:
print("The user opened the app from the notification")
completionHandler()
default:
print("The default case was called")
}
}
}
