Discussion
This method is called in response to a message sent by the counterpart process using the sendMessage(_:replyHandler:errorHandler:) method. This specific method is called when the counterpart specifies nil for the reply handler, indicating that it does not want a response. Use this method to process the message data and take whatever further actions are needed.
Use messages to communicate quickly with the counterpart process. Messages can be sent and received only while both processes are active and running.
The delivery of multiple messages occurs serially, so your implementation of this method does not need to be reentrant. This method is called on a background thread of your app.
