# update()

Saves your changes to the promoted product’s visibility.

```
func update() async throws
```

## Discussion

If you change the [`visibility`](/documentation/StoreKit/Product/PromotionInfo/visibility-swift.property) value by setting it directly, call [`update()`](/documentation/StoreKit/Product/PromotionInfo/update()) to save your changes to the App Store server. Changes take effect after you call [`update()`](/documentation/StoreKit/Product/PromotionInfo/update()) or [`updateAll(_:)`](/documentation/StoreKit/Product/PromotionInfo/updateAll(_:)).
