Swift 3.0 Syntax change for UIUserNotificationSettings

Question

I am using swift 3.0 and am trying to add badge numbers to my app. I believe the correct way to do this is similar to what is below.

application.registerUserNoti

From what I understand, UIUserNotificationSettings has been deprecated for iOS 10.0. It is now recommended that you use the UNUserNotificationCenter.

Here's what I did to make sure my code was up to date:

1) Import the UserNotifications framework in your AppDelegate

import UserNotifications

2) Inside the didFinishLaunchingWithOptions function inside the AppDelegate, add the following:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in

        if granted {
            UIApplication.shared.registerForRemoteNotifications()
        }

    }

    return true
}

Once you have the notifications registered and allowed, you can change the badge number at any point:

UIApplication.shared.applicationIconBadgeNumber = value

This worked for me, I just tested it by sending a remote notification to my phone, and it worked fine. Hope this helps.
