Notifications

Summary:
I'm trying to schedule a couple local notifications in a loop (see attached project). Each notification (which triggers immediately) is intended to increment the app's badge number. However, running this does not seem to increment it properly; if I schedule 5 notifications the badge becomes "1", not "5". The issue appears to be that there is a delay in the updating applicationIconBadgeNumber; putting any sort of delay (for example, a sleep or a breakpoint) will resolve the issue.

Steps to Reproduce:
(Faulty results)
1. Run the attached code.
2. Simulate a background fetch (select it from Xcode's "Debug" menu)
3. View the badge number.

(Expected results)
4. Navigate to application(_:performFetchWithCompletionHandler:) in AppDelegate.swift.
5. Find the usleep line.
6. Uncomment it.
7. Run the steps 1-3.

Expected Results:
The application badge icon will increase by 1 each time.

Actual Results:
The application badge icon will end up as 1 (or some other small number).

Version:
iOS 10.3 [14E269]

Notes:
I apologize for the use of UINotification; I was too lazy to figure out how UserNotifications worked. I set the deployment target to 9.3 to get rid of the warnings.

Configuration:
iOS Simulator
