enum · iOS 17.0+ · SDK 27.1
enum ProductIconPhaseThe current phase of the asynchronous loading operation of the promotional image for a given App Store product. When you create a ``ProductView`` instance with the phase-based initializer, you define the appearance of the product view's icon using a content closure. StoreKit calls the closure with a phase value at different points during the load operation of the promoted IAP image you've set up in App Store Connect to indicate the current state. Use the phase to decide what to draw. For example, you can draw the loaded image if it exists, a view that indicates an error, or a placeholder: ``` ProductView(id: "com.example.product") { phase in switch phase { case .success(let promotedIcon): promotedIcon case .failure(let error): MyErrorView(error) case .unavailable: MyFallbackIcon() case .loading: MyPlaceholderIcon() } } ```
get promotionalIcon(): (_SwiftUICore_Image) | nullvar promotionalIcon: Image? { get }The promotional image if the loading task was successful. Use this as a convenience to access the product value in code that doesn't depend on the reason the icon can't be accessed. The value is `nil` while the icon is loading, or if the icon can't be accessed for any reason.
get error(): (NativeError) | nullvar error: (any Error)? { get }The error if the loading task was unsuccessful. Use this as a convenience to access the error value in code that assumes there has been a promotional image set up for the product in App Store Connect. The value is `nil` while the icon is loading, if the icon has successfully loaded, or if the promotional image for the product has not been set up in App Store Connect.
