# raise()

Raises the receiver, causing program flow to jump to the local exception handler.

## Declaration

```swift
func raise()
```

## Discussion

Discussion When there are no exception handlers in the exception handler stack, unless the exception is raised during the posting of a notification, this method calls the uncaught exception handler, in which last-minute logging can be performed. The program then terminates, regardless of the actions taken by the uncaught exception handler.
