问题
My App receives a local notification Not a remote Notification. How can I know if the app is opened by pressing the notification and not the app icon when the app is killed( Not running in background or foreground). Previosuly, I used the following method
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
if ((launchOptions?[UIApplication.LaunchOptionsKey.loaclNotification] != nil))
{
print("here")
}
}
however this function is deprecated as of iOS 10
[UIApplication.LaunchOptionsKey.loaclNotification] != nil)
and apple documentation suggests to use the following method.
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
}
This method is called only when the app is in the foreground or background. Any help will be appreciated

As you said, implement the UNUserNotificationCenterDelegate method didReceive. If the user tapped your notification, it will be called, launching your app if it isn’t running.
