# service()

Returns the singleton listener used to listen for incoming connections in an XPC service.

## Declaration

```swift
class func service() -> NSXPCListener
```

## Discussion

Discussion Calling the resume method on the returned object starts the listener and never returns. This method is typically called at the end of your main function. note: This method requires that the XPC service has the appropriate configuration in its Info.plist file.
