# netServiceBrowser(_:didFindDomain:moreComing:)

Tells the delegate the sender found a domain.

```
optional func netServiceBrowser(_ browser: NetServiceBrowser, didFindDomain domainString: String, moreComing: Bool)
```

## Parameters

`browser`

Sender of this delegate message.

`domainString`

Name of the domain found by `netServiceBrowser`.

`moreComing`

<doc://com.apple.documentation/documentation/Swift/true> when `netServiceBrowser` is waiting for additional domains. <doc://com.apple.documentation/documentation/Swift/false> when there are no additional domains.

## Discussion

The delegate uses this message to compile a list of available domains. It should wait until `moreDomainsComing` is <doc://com.apple.documentation/documentation/Swift/false> to do a bulk update of user interface elements.
