```

## Discussion

An Apple event is being handled on the current thread if [`currentAppleEvent`](/documentation/Foundation/NSAppleEventManager/currentAppleEvent) does not return `nil`. Returns `nil` otherwise. This descriptor, including any mutations, will be returned to the sender of the current event when all handling of the event has been completed, if the sender has requested a reply. The effects of retaining the descriptor are undefined; it may be copied, but mutations of the copy are not returned to the sender of the current event.
