# fire()

Causes the timer’s message to be sent to its target.

## Declaration

```swift
func fire()
```

## Discussion

Discussion You can use this method to fire a repeating timer without interrupting its regular firing schedule. If the timer is non-repeating, it is automatically invalidated after firing, even if its scheduled fire date has not arrived.
