How to schedule local notification from iOS14 widget? - swift

Question

I would like to schedule a local notification from iOS14 widget.
How can I do it?
I tried implementing the following:
let center = UNUserNotificationCenter.current()
center.delegate = self
let content = UNMutableNotificationContent()
content.title = "Some Title"
content.body = "Some Body"
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: true)
let request = UNNotificationRequest(identifier: UUID().uuidString,
content: content, trigger: trigger)
center.add(request) { (error) in
if error != nil {
// Handle any errors.
}

I did with this.
func createDate(day: Int, month : Int, hour: Int, minute: Int, year: Int)->Date{
var components = DateComponents()
components.hour = hour
components.minute = minute
components.year = year
components.day = day
components.month = month
components.timeZone = .current
let calendar = Calendar(identifier: .gregorian)
return calendar.date(from: components)!
}
// 📢///CreateNitification
func scheduleNotification(at date: Date, identifierUnic : String, body: String, titles:String) {
let triggerWeekly = Calendar.current.dateComponents([.day, .month, .hour,.minute, .year], from: date)
let trigger = UNCalendarNotificationTrigger(dateMatching: triggerWeekly, repeats: true)
let content = UNMutableNotificationContent()
content.title = titles
content.body = body
content.sound = UNNotificationSound.default
content.categoryIdentifier = "todoList2"
let request = UNNotificationRequest(identifier: identifierUnic, content: content, trigger: trigger)
// UNUserNotificationCenter.current().delegate = self
/// UNUserNotificationCenter.current().removeDeliveredNotifications(withIdentifiers: ["textNotification2"])
/// UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
UNUserNotificationCenter.current().add(request) {(error) in
if let error = error {
print(" We had an error: \(error)")
}}
}
// Call
func callNotifications(){
UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
let adte = createDate(day: 3, month: 6, hour: 16, minute: 51, year: 2021)
scheduleNotification(at: adte, identifierUnic: UUID().uuidString, body: "Widgets on Work", titles: "check 123")
}
func getTimeline(in context: Context, completion: #escaping (Timeline<Entry>) -> ()) {
callNotifications()
var entries: [SimpleEntry] = []
// Generate a timeline consisting of five entries an hour apart, starting from the current date.
let currentDate = Date()
for hourOffset in 0 ..< 5 {
let entryDate = Calendar.current.date(byAdding: .hour, value: hourOffset, to: currentDate)!
let entry = SimpleEntry(date: entryDate)
entries.append(entry)
}
let timeline = Timeline(entries: entries, policy: .atEnd)
completion(timeline)
}
Notification is working fine
but one thing is pending, how can I call UNUserNotificationCenter.current().delegate = self?
Thanks
