# reportVolatileMetadataUpdate(_:)

Updates the volatile metadata within the current state without beginning a new transition.

```
final func reportVolatileMetadataUpdate(_ updatedMetadata: VolatileMetadata?)
```

## Parameters

`updatedMetadata`

The updated volatile metadata, or `nil` to clear volatile context
without ending the current state.

## Discussion

Use this method to update rapidly-changing data — such as a progress value or a running
count — while staying within the same state. If no state is currently active, this call
is a no-op. Calling this method more frequently than user interaction timescales can
trigger rate limiting, causing updates to go unlogged.
