registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later

Question

When trying to register for push notifications under iOS 8.x:

application.registerForRemoteNotificationTypes(UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound)

I get the following error:

registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later.

Any ideas what is the new way of doing it? It does work when I run this Swift app on iOS 7.x.

EDIT

On iOS 7.x when I include the conditional code I get (either SystemVersion conditional or #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000)

dyld: Symbol not found: _OBJC_CLASS_$_UIUserNotificationSettings

Answer 1

For iOS<10

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
    //-- Set Notification
    if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)]) 
    {
           // iOS 8 Notifications
           [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

           [application registerForRemoteNotifications];
    }
    else
    {
          // iOS < 8 Notifications
          [application registerForRemoteNotificationTypes:
                     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
    }

     //--- your custom code
     return YES;
}

For iOS10
