# export(to:metadata:)

Exports this temporal transformer as a CoreML model with user-supplied metadata.

```
func export(to url: URL, metadata: ModelMetadata) throws
```

## Parameters

`url`

The location to write the model into.

`metadata`

Contextual user-provided information.

## Discussion> Note: By default this method exports .mlpackage files. You can export a .mlmodel file by specifying that as
> the URL file extension. But if you specify .mlmodel and the transformer doesn’t support it, this method will
> throw an error.
