Overview

The iOS & iPadOS 15.4 SDK provides support to develop apps for iPhone, iPad, and iPod touch devices running iOS & iPadOS 15.4 beta. The SDK comes bundled with Xcode 13.3 beta, available from Beta Software Downloads. For information on the compatibility requirements for Xcode 13.3, see Xcode 13.3 Beta Release Notes.

Apple Pay

New Features in iOS & iPadOS 15.4 Beta

• Developers can express payment network preference in [PKPaymentRequest](/documentation/passkit/pkpaymentrequest).

This won’t override the user’s default card selection, but if the card is multi-SSD, then the network preference order determines which SSD is selected. (80827905)

StoreKit

New Features in iOS & iPadOS 15.4 Beta

• [SKTestSession](/documentation/storekittest/sktestsession) has three new methods to simulate a subscription requiring price increase consent, simulate consenting to a pending price increase, and simulate declining a price increase in automated tests. (84556183)
• SKTestSession has two new Boolean properties to simulate billing retry and grace period in automated tests. You can identify and simulate the resolution of billing retry issues using the same APIs as interrupted purchases. (83956205)
• Users can now test the billing retry and grace period states using StoreKit Testing in Xcode. Use Xcode 13.3 or later to enable billing retry testing and toggle whether the app offers a grace period. Use [isInBillingRetry](/documentation/storekit/product/subscriptioninfo/renewalinfo/3749502-isinbillingretry) and [gracePeriodExpirationDate](/documentation/storekit/product/subscriptioninfo/renewalinfo/3749500-graceperiodexpirationdate) to handle these states in the app. (83938270)
• You can now test offer codes with StoreKit Testing in Xcode. Configure offers for codes in Xcode 13.3 or later, and test redeeming them using [presentCodeRedemptionSheet()](/documentation/storekit/skpaymentqueue/3566726-presentcoderedemptionsheet). (63692551)
• Users can test subscription price increase behavior using StoreKit Testing in Xcode. Use Xcode 13.3 or later to set a price increase, then use [paymentQueueShouldShowPriceConsent(_:)](/documentation/storekit/skpaymentqueuedelegate/3521328-paymentqueueshouldshowpriceconse), [showPriceConsentIfNeeded()](/documentation/storekit/skpaymentqueue/3521327-showpriceconsentifneeded), and [priceIncreaseStatus](/documentation/storekit/product/subscriptioninfo/renewalinfo/3822292-priceincreasestatus) in the app. (58770817)
• StoreKit error types now conform to [LocalizedError](/documentation/foundation/localizederror). (78735204)
• Some types in StoreKit now have a localizedDescription' read-onlyStringinstance property. This property can be used to get a human-readable description of the value, localized for the device’s current locale. These types include:Product.ProductType`, [Product.SubscriptionInfo.RenewalState](/documentation/storekit/product/subscriptioninfo/renewalstate), [expirationReason](/documentation/storekit/product/subscriptioninfo/renewalinfo/3749499-expirationreason), [priceIncreaseStatus](/documentation/storekit/product/subscriptioninfo/renewalinfo/3822292-priceincreasestatus), [Transaction.OfferType](/documentation/storekit/transaction/offertype), [Product.SubscriptionOffer.OfferType](/documentation/storekit/product/subscriptionoffer/offertype), [Product.SubscriptionOffer.PaymentMode](/documentation/storekit/product/subscriptionoffer/paymentmode), [Product.SubscriptionPeriod.Unit](/documentation/storekit/product/subscriptionperiod/unit), [Transaction.RevocationReason](/documentation/storekit/transaction/revocationreason), and [Transaction.OwnershipType](/documentation/storekit/transaction/ownershiptype).
