# SubscriptionStoreControlStyleConfiguration.Option Properties of an auto-renewable subscription option to merchandise. ``` @dynamicMemberLookup struct Option ``` ## Overview You use `SubscriptionStoreControlStyleConfiguration.Option` very similarly to [`Product`](/documentation/StoreKit/Product) values, with some important differences: - The `offer` property indicates the offer that applies to the purchase. Display the terms of the `offer`, and ignore offer properties on [`Product.SubscriptionInfo`](/documentation/StoreKit/Product/SubscriptionInfo), such as [`introductoryOffer`](/documentation/StoreKit/Product/SubscriptionInfo/introductoryOffer). - If the `offer` is `nil`, no offer applies to the purchase. - Call the [`subscribe()`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/subscribe()) method when a customer activates a control to subscribe to a subscription option, instead of methods on [`Product`](/documentation/StoreKit/Product), such as [`purchase(confirmIn:options:)`](/documentation/StoreKit/Product/purchase(confirmIn:options:)-6dj6y). - Access the decorative icon using the [`icon`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/icon) property. `SubscriptionStoreControlStyleConfiguration.Option` is a dynamic member lookup type, so you don’t need to use [`subscription`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/subscription) directly to access the properties of the `Product` value. Instead, access the properties of `Product` or [`Product.SubscriptionInfo`](/documentation/StoreKit/Product/SubscriptionInfo) directly on the `Option` value. In the example below, the [`displayName`](/documentation/StoreKit/Product/displayName) property is available on `Option` to use as the button label: ```swift struct DisplayNameButtonsControlStyle: SubscriptionStoreControlStyle { func makeBody(configuration: Configuration) -> some View { ForEach(configuration.options) { option in Button(option.displayName, action: option.subscribe) } } } ``` ## Topics ### Getting the subscription product and offer [`var subscription: Product`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/subscription) The auto-renewable subscription to merchandise. [`var id: Product.ID`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/id) The product ID of the auto-renewable subscription. [`var activeOffer: Product.SubscriptionOffer?`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/activeOffer) The subscription offer the customer is eligible for, and that applies to the subscription option. ### Getting the icon [`var icon: SubscriptionStoreControlStyleConfiguration.Icon?`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/icon) The subscription option’s icon. ### Purchasing a subscription option [`func subscribe()`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/subscribe()) Initiates a purchase when a customer activates a control to subscribe to the option. ### Looking up dynamic members [`subscript(dynamicMember _: KeyPath) -> T?`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/subscript(dynamicMember:)-8sl2m) Facilitates accessing optional subscription properties on an option value. [`subscript(dynamicMember _: KeyPath) -> T?`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/subscript(dynamicMember:)-wjww) Facilitates accessing subscription properties on an option value. [`subscript(dynamicMember _: KeyPath) -> T`](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/subscript(dynamicMember:)-9g2sm) Facilitates accessing product properties on an option value. ### Default Implementations [Identifiable Implementations](/documentation/StoreKit/SubscriptionStoreControlStyleConfiguration/Option/Identifiable-Implementations) ## Relationships ### Conforms To [`Equatable`](/documentation/Swift/Equatable) [`Hashable`](/documentation/Swift/Hashable) [`Copyable`](/documentation/Swift/Copyable) [`Identifiable`](/documentation/Swift/Identifiable) [`Escapable`](/documentation/Swift/Escapable) --- Copyright © 2026 Apple Inc.
