UserNotifications Extension Service UNNotificationAction didReceive action delegate not getting called. - swift

Question

I am creating Notification Service extension for local notification with UNNotificationAction but on tap of it delegate not getting called.
userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void)
here are my 3 actions
// Define Actions
let actionReadLater = UNNotificationAction(identifier: Notification.Action.readLater, title: "Read Later", options: [])
let actionShowDetails = UNNotificationAction(identifier: Notification.Action.showDetails, title: "Show Details", options: [.foreground])
let actionUnsubscribe = UNNotificationAction(identifier: Notification.Action.unsubscribe, title: "Unsubscribe", options: [.destructive, .authenticationRequired])
// Define Category
let tutorialCategory = UNNotificationCategory(identifier: Notification.Category.tutorial, actions: [actionReadLater, actionShowDetails, actionUnsubscribe], intentIdentifiers: [], options: [])
// Register Category
UNUserNotificationCenter.current().setNotificationCategories([tutorialCategory])
to schedule notification I am using
private func scheduleLocalNotification() {
// Create Notification Content
let notificationContent = UNMutableNotificationContent()
// Configure Notification Content
notificationContent.title = "Cocoacasts"
notificationContent.subtitle = "Local Notifications"
notificationContent.body = "In this tutorial, you learn how to schedule local notifications with the User Notifications framework."
notificationContent.userInfo = ["customNumber": 100]
// Set Category Identifier
notificationContent.categoryIdentifier = Notification.Category.tutorial
// Add Trigger
let notificationTrigger = UNTimeIntervalNotificationTrigger(timeInterval: 10.0, repeats: false)
// Create Notification Request
let notificationRequest = UNNotificationRequest(identifier: "exampleNotification", content: notificationContent, trigger: notificationTrigger)
// Add Request to User Notification Center
UNUserNotificationCenter.current().add(notificationRequest) { (error) in
if let error = error {
print("Unable to Add Notification Request (\(error), \(error.localizedDescription))")
}
}
}
My extension is getting displayed but actions are not getting triggered & without extension actions are working fine.

Try something like that:
class NotificationViewController: UIViewController, UNNotificationContentExtension {
#IBOutlet var label: UILabel?
override func viewDidLoad() {
super.viewDidLoad()
// Do any required interface initialization here.
preferredContentSize = CGSize.init(width: self.view.bounds.width / 2, height: self.view.bounds.height / 5)
}
func didReceive(_ notification: UNNotification) {
self.label?.text = "Extension"
}
// Implement this method
func didReceive(_ response: UNNotificationResponse, completionHandler completion: #escaping (UNNotificationContentExtensionResponseOption) -> Void) {
if response.notification.request.content.categoryIdentifier == "yourCategory" {
switch response.actionIdentifier {
case "first":
// Do something
completion(.dismissAndForwardAction)
case "second":
// Do something
completion(.dismissAndForwardAction)
default:
break;
}
}
}
}
You should implement the UNNotificationContentExtension's method:
func didReceive(_ response: UNNotificationResponse, completionHandler completion: #escaping (UNNotificationContentExtensionResponseOption) -> Void) {}
And inside of this block you can check your actions. Hope it helps.
