Hello, I noticed the Product.SubscriptionInfo subscriptionPeriod (of type Product.SubscriptionPeriod) is different for the same product between StoreKit Testing in Xcode and the sandbox/App Store (production) environment. For a “1 week” auto-renewable subscription, we get the following: StoreKit Testing in Xcode: 1 week gives a subscriptionPeriod with value of 1 and a unit of Product.SubscriptionPeriod.Unit.week Sandbox/App Store: 1 week gives a subscriptionPeriod with value of 7 and a unit of Product.SubscriptionPeriod.Unit.day This created issues in my app because I used the localizedDescription of a Product.SubscriptionPeriod to display a text similar to “$4.99 per week”. This is what I obtain with the StoreKit Testing in Xcode, but in the Sandbox/App Store environment, it displays “$4.99 per day” (because the subscriptionPeriod is “7 Days” and the unit is then .day). Obviously, this is not what I wanted to display. Other periods like “1 month”, “2 months”, “3 months”, “6 months, and “1 year”, the period provided by both StoreKit Testing and Sandbox/App Store correspond to the period unit specified in App Store Connect. In addition, I want to report that for a weekly subscription/offer or a 2 weeks offer, Product.SubscriptionInfo.subscriptionPeriod or Product.SubscriptionOffer.period == .weekly or .everyTwoWeeks is always false. We observe the following: With Sandbox or App Store live production: 1 week, Product.SubscriptionInfo.subscriptionPeriod == .weekly is false (because it’s “7 days”) 1 week, Product.SubscriptionOffer.period == .weekly is false (because it’s “7 days”) 2 weeks (offer), Product.SubscriptionInfo.subscriptionPeriod == .everyTwoWeeks is false (because it’s “14 days”) 2 weeks (offer), Product.SubscriptionOffer.period == .everyTwoWeeks is false (because it’s “14 days”) But with an Xcode StoreKit configuration file: 1 week, Product.SubscriptionInfo.subscriptionPeriod == .weekly is true (because it’s “1 week”) 1 week, Product.SubscriptionOffer.period == .weekly is true (because it’s “1 week”) 2 weeks, Product.SubscriptionInfo.subscriptionPeriod == . everyTwoWeeks is true (because it’s “2 weeks”) 2 weeks, Product.SubscriptionOffer.period == . everyTwoWeeks is true (because it’s “2 weeks”) So in sandbox and production, .weekly and .everyTwoWeeks is never possible. If someone from Apple could check the feedback FB19605865 🙂 Thank you Regards, Axel, @alpennec Code: do { let productIDs: [String] = ["revenueSocks_weekly_trial"] let products: [StoreKit.Product] = try await Product.products (for: productIDs) let weeklySubscription: StoreKit.Product = products.first! let displayPrice: String = weeklySubscription.displayPrice // For a weekly subscription in App Store Connect // With an Xcode StoreKit configuration file: subscriptionPeriod unit is Week (week), value is 1 → "1 Week" // With the Sandbox + App Store: subscriptionPeriod unit is Day (.day), value is 7 → "7 Days" let unitString: String = weeklySubscription.subscription!.subscriptionPeriod.unit.localizedDescription print("\(displayPrice) per \(unitString.localizedLowercase)") // StoreKit configuration file → "$4.99 per week" // Sandbox + App Store → "$4.99 per day" } catch { print(error) }
