# NSUpdateDynamicServices()

Causes the services information for the system to be updated.

## Declaration

```swift
func NSUpdateDynamicServices()
```

## Discussion

Discussion Used by a service-providing application to reregister the services it is willing to provide. To do this, you create a bundle with the extension “.service” and place it in the application’s path or ~/Library/Services. The content of the bundle is identical to a normal service bundle. You then call this function. It is only necessary to call this function if your program adds dynamic services to the system.
