How to handle UserNotification through widget iOS14 to main app in swift? - swift

Question

I have an iOS app with widget iOS 14 where I send UserNotifications from both sides. On main app side all UNUserNotificationCenterDelegate is working fine. On widget side when I fetched events from calendar then UserNotifications are triggered. When I'm received notification in main-app side and click on it, then didReceive response: UNNotificationResponse delegate or other delegates did not called and also did not called in widget side.
here is my code in Widgets
class NotificationCenter: NSObject, ObservableObject {
#Published var dumbData: UNNotificationResponse?
override init() {
super.init()
UNUserNotificationCenter.current().delegate = self
}
}
extension NotificationCenter: UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .sound, .badge])
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
completionHandler()
}
func userNotificationCenter(_ center: UNUserNotificationCenter, openSettingsFor notification: UNNotification?) {
}
func scheduleNotification(at date: Date, identifierUnic : String, body: String, titles:String) {
UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
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().add(request) {(error) in
if let error = error {
print(" We had an error: \(error)")
}}
}
}
//and fire in
#ObservedObject var notificationCenter: NotificationCenter
func getTimeline(in context: Context, completion: #escaping (Timeline<Entry>) -> ()) {
eventManager.checkPermission { (eventArray) in
print(eventArray)
if eventArray.count > 0{
for item in eventArray{
notificationCenter.scheduleNotification(at: item.startDate ?? Date(), identifierUnic: item.eventIdentifier ?? "", body: item.title, titles: item.title)
}
}
}
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: .second, value: hourOffset, to: currentDate)!
let entry = SimpleEntry(date: entryDate)
entries.append(entry)
}
let timeline = Timeline(entries: entries, policy: .atEnd)
completion(timeline)
}
On Main App Side
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
print("userInfo \(userInfo)")
}
What is missing in it?
Is it right way to handle UserNotification on two Targets?
Any other way to do this?
Please let me know?
Thank you

I have a similar situation that I still can't figure out how to do... I have a widget that will display calendar events. How can I refresh the widget when calendar changed? I tried to use notificationCenter but don't know where to put it. What I want to do is that when there is a calendar change, my widget should be reloaded (refresh timeline.)
Thank you for your help.
