在iOS Swift 4中重置FCM徽章计数

Question

How do I reset the FCM badge count in iOS swift 4? Right now I call this line of code:

UIApplication.shared.applicationIconBadgeNumber = 0

which temporarily sets the badge count to 0, but when I receive a new notification the count starts back at the previous count.

IE 100, open the app and reset the count to 0 as above. Then when I get a new notification the badge goes to 101.

Is there something different I need to do for FCM? I have ensured that the server is sending the correct badge count.

I ended up finding the issue to be a syntax error when clearing the notification count server side. Thanks for your suggestions.
