Instance Method


Creates a notification with information, and posts it to the receiver.


func postNotificationName(_ name: NSNotification.Name, object: String?, userInfo: [AnyHashable : Any]? = nil, options: DistributedNotificationCenter.Options = [])



Name of the notification to post. Must not be nil.


Sender of the notification. May be nil.


Dictionary containing additional information. May be nil.


Specifies how the notification is posted to the task and when to deliver it to its observers. See Notification Posting Behavior for details.


The userInfo dictionary is serialized as a property list, so it can be passed to another task. In the receiving task, it is deserialized back into a dictionary. This serialization imposes some restrictions on the objects that can be placed in the userInfo dictionary. See XML Property Lists for details.
