# netServiceWillPublish(_:)

Notifies the delegate that the network is ready to publish the service.

## Declaration

```swift
optional func netServiceWillPublish(_ sender: NetService)
```

## Parameters

- `sender`: The service that is ready to publish.

## Discussion

Discussion Publication of the service proceeds asynchronously and may still generate a call to the delegate’s netService(_:didNotPublish:) method if an error occurs.
