var subscriptionGroupIdentifier: String? { get }
```

## Discussion

Discussion Auto-renewable subscriptions always belong to a subscription group. You create the subscription group identifiers in App Store Connect before you create and add an auto-renewable subscription. For more information about subscription groups, see Offer auto-renewable subscriptions. This property is nil if the SKProduct isn’t an auto-renewable subscription.
