didTerminateNotification

Declaration

class let didTerminateNotification: NSNotification.Name

Discussion

The notification object is the NSTask object that the system terminated. This notification doesn’t contain a userInfo dictionary.

The system posts this notification from the thread in which the NSTask object called launch(). When launching a task from a secondary thread or background queue, you can use the terminationHandler property instead for greater control over the execution context of any operations to be performed after the task finishes.

This notification can be posted either when the task has exited normally or as a result of terminate() being sent to the NSTask object. If the NSTask object gets released, however, this notification won’t get sent, as the port the message would have been sent on was released as part of the task release. The observer method can use terminationStatus to determine why the task died.
