# resolve(withTimeout:)

Starts a resolve process of a finite duration for the service.

```
func resolve(withTimeout timeout: TimeInterval)
```

## Parameters

`timeout`

The maximum number of seconds to attempt a resolve. A value of 0.0 indicates no timeout and a resolve process of indefinite duration.

## Discussion

During the resolve period, the service sends [`netServiceDidResolveAddress(_:)`](/documentation/Foundation/NetServiceDelegate/netServiceDidResolveAddress(_:)) to the delegate for each address it discovers that matches the service parameters. Once the timeout is hit, the service sends [`netServiceDidStop(_:)`](/documentation/Foundation/NetServiceDelegate/netServiceDidStop(_:)) to the delegate. If no addresses resolve during the timeout period, the service sends [`netService(_:didNotResolve:)`](/documentation/Foundation/NetServiceDelegate/netService(_:didNotResolve:)) to the delegate.

## See Also

[`addresses`](/documentation/Foundation/NetService/addresses)

A read-only array containing `NSData` objects, each of which contains a socket address for the service.
