How to register push notifications in Swift 3?

  • 772

Push notifications in versions prior to Xcode8 worked correctly, but when migrating to swift 3 it no longer registers the Token. My code is the following:

application.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil));
            application.registerForRemoteNotifications()

    You have to import the framework UserNotificationsand add the delegate UNUserNotificationCenterDelegatein the AppDelegate.swift file

    Request user permission

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
     let center = UNUserNotificationCenter.current()
     center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
            // Enable or disable features based on authorization.
     }
     application.registerForRemoteNotifications()
     return true
}

    Get the Token 

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {

    let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
    print(deviceTokenString)
}
