iOS LocalNotification ambiguous reference error

i am get this error there something that i should define.

Error Message:
error CS0104: LocalNotification' is an ambiguous reference between UnityEngine.LocalNotification’ and `UnityEngine.iOS.LocalNotification’


        LocalNotification notif = new LocalNotification();
	notif.fireDate = DateTime.Now.AddSeconds(60);
	notif.alertAction = "Alien Rescue Saga";
	notif.alertBody = "Hello!";

Making it simple, you have two classes with the same name. You should disambiguate the reference by specifing the full package for the desired one.

UnityEngine.iOS.LocalNotification notif = new UnityEngine.iOS.LocalNotification();
