Object Capture
New Features

A new manual bounding box flow is now initiated if automatic object detection fails to find an object, particularly in cases where there is no salient ground plane. In this flow, the user is expected to utilize the standard manual bounding box controls to indicate the bounding box of the object to capture by adjusting the provided starting box placed in the world in front of the user. You can determine if this mode has been activated by observing for the new element .objectNotDetected, which will be added to the ObjectCaptureSession's Feedback set when the manual flow has been activated. You can use this to provide notification and/or instructions to the user about this manual box flow as desired. (113474123)

New Features

StoreKit
New Features

In StoreKit testing in Xcode, a billing error StoreKit message will be sent when a subscription tries to renew while the Enable Billing Retry on Renewal setting is enabled in the StoreKit configuration file. Use the messages listener API to control when StoreKit messages are displayed in your app. (101869442)

productDescriptionHidden(_:) API can be used to configure the visibility of product descriptions in ProductView, StoreView and SubscriptionStoreView instances within a view hierarchy. When building with Xcode 15.3, the view modifier can be used even if your app is running on iOS 17.0, iPadOS 17.0, macOS 14.0, tvOS 17.0, watchOS 10.0, visionOS 1.0, or later.

When implementing a product view style, it can support this new view modifier by checking the descriptionVisibility property on the configuration value. (110414819) (FB12261973)

You can use SubscriptionStoreView to present promotional offers by adding the subscriptionPromotionalOffer(offer:signature:) modifier.

If you're already using inAppPurchaseOptions(_:) modifier to support promotional offers for StoreKit views, you should adopt the new API instead when your app is running on iOS 17.4, iPadOS 17.4, macOS 14.4, tvOS 17.4, watchOS 10.4, visionOS 1.1 or later. Do not use both APIs to apply a promotional offer for the same view. (115358806)

Resolved Issues

Fixed: The isEligibleForIntroOffer property and isEligibleForIntroOffer(for:) method now reflect ineligibility in cases where a customer would otherwise be eligible for the offer if they weren't actively subscribed. This means a customer which is not currently eligible for an introductory offer may become eligible in the future.

Customers who redeem an introductory offer for a given subscription group will continue to never be eligible for another introductory offer in that subscription group. You can detect this case this by checking if any one transaction with a matching subscriptionGroupID has the type property on offer set to introductory . (103604770) (FB11889732)

Fixed an issue causing SKAdNetwork versions 2.2 and 3.0 to not accept impressions or send postbacks. (121223565)

Fixed an issue causing some approved Ask to Buy purchases to fail. (121249405)

Popover presentations now automatically dismiss if they go outside the safe area. (100811375)

Resolved Issues

Fixed: Resolved an issue with programmatically present an alert or sheet simultaneously with dismissing another sheet. The new alert or sheet would not show but now it will. If you have code that presents the same sheet programmatically from multiple places in your view hierarchy at the same time, that sheet might no longer appear. Make sure that any sheet modifiers that are in the view hierarchy at the same time use distinct isPresented or item bindings. (117475214)

WebKit

Fixed HTML content not displaying in a Simulator, affecting projects using the web extension project template. (121338366)
