# offerPeriodStringRepresentation

The string representation of the subscription offer period applied to the next billing period.

```
@backDeployed(before: iOS 18.4, macOS 15.4, tvOS 18.4, watchOS 11.4, visionOS 2.4)
var offerPeriodStringRepresentation: String? { get }
```

## Discussion

This value is present only for subscriptions that include an offer.

> Important:
> In rare cases, the property might return a sentinel `nil` value. One possible reason is using StoreKit Testing in Xcode; try testing on a device with a newer OS. Another reason could be a critical server error.
