iOS 11.2 brings support for Apple Pay Cash as well as Introductory Pricing for Auto-Renewable Subscriptions.
Soon, you’ll be able to offer new customers a discounted introductory price for your auto-renewable subscriptions on the App Store. iOS 11.2 introduces new classes (SKProductDiscount and SKProductSubscriptionPeriod) and new properties on SKProduct (subscriptionPeriod and introductoryPrice) to provide details on the introductory pricing and billing period you’ve selected for your auto-renewable subscriptions. You can use these new API additions to localize and display information about introductory pricing to your users. You’ll be able to configure introductory pricing on your in-app purchase page in iTunes Connect soon.
