Local banner notification for terminating App

Question

I want to show banner notification when user quits the Application. And on tapping that banner I want my Application to open.

func showBanner() {

    UIApplication.shared.cancelAllLocalNotifications()

    let notif = UILocalNotification.init()
    notif.alertBody = "Your Message Here..."
    localNotif.soundName = UILocalNotificationDefaultSoundName

    UIApplication.shared.presentLocalNotificationNow(notif)
}

If I put this code in applicationDidEnterBackground it works fine; But, when I put it in applicationWillTerminate, it doesn't.

Any workaround?

EDIT:

Added fireDate like following:

var dc = DateComponents()
dc.second = 2 // 2 seconds from current date time
notif.fireDate = Calendar.current.date(byAdding: dc, to: Date())

Still not working. Any idea?

@Anbu.Karthik It works when I put it withing `applicationDidEnterBackground` But, it doesn't work when I put it within `applicationWillTerminate` as mentioned in queston. — sweta.me, Feb 21 '17 at 13:07

@Anbu.Karthik The link you provided says `applicationWillTerminate`. But, it's not working. That's what the question is. — sweta.me, Feb 21 '17 at 13:09

The same code works when I set in App communicates using CoreBluetooth in info.plist for Requires Background Modes.

Got the hint from This Answer

Let's hope, Apple does not reject my App.

no guarantee that applicationWillTerminate will ever get called may that is the reasone your code not working . so if your need to do anything before app exist then call applicationDidEnterBackground

But, I want the notification to appear only when the application is terminated. Not when it's in background. Any workaround? – sweta.me Feb 21 '17 at 12:57
How would I know? I don't even have that much reps to downvote. :D Btw, you can post the answer as comment to question, as it is not actually an answer. – sweta.me Feb 21 '17 at 13:02
