macOS Sonoma 14.2 Release Notes

Update your apps to use new features, and test your apps against API changes.

Overview

The macOS 14.2 SDK provides support to develop apps for Mac computers running Sonoma 14.2. The SDK comes bundled with Xcode 15.1, available from the Mac App Store. For information on the compatibility requirements for Xcode 15.1, see Xcode 15.1 Release Notes.

iMessage Contact Key Verification

New Features

  • With iMessage Contact Key Verification, users can choose to further verify that they are messaging only with the people they intend. iMessage Contact Key Verification uses Key Transparency to enable automatic verification that the iMessage key distribution service returns device keys that have been logged to a verifiable and auditable map. When a user enables the feature, they will be notified about any validation errors directly in the Messages conversation transcript and Apple ID Settings.

    For even higher security, iMessage Contact Key Verification users can compare a contact verification code in person, on FaceTime, or through another secure call. They can also choose to create or edit a contact and save a public key to turn on iMessage Contact Key Verification with that person.

    All devices signed into your iCloud account must be on the minimum supported version of iOS 17.2 Beta, macOS 14.2 Beta, or watchOS 10.2 Beta. If you wish to keep using other devices on older versions of the OS, you will need to sign out of iMessage on these devices in order to enable contact key verification. (111356044)

Resolved Issues

  • Fixed: When verifying another user, Contact Verification Code will not show unless both users are on beta 4 or higher. (114462363)

  • Fixed: After verifying a contact, the verificaton checkmark might not show up in Messages app. (116142336)

  • Fixed: Users might see an error to Turned Off transcript every few hours. (116405131)

  • Fixed: Users might see that they’re are not eligible to enable Contact Key Verification on some of their upgraded devices. (117044482)

Known Issues

  • The Learn More links do not link to Knowledge Base articles during Beta. (101563811)

Messages

Resolved Issues

  • Fixed: Unlocalized string shown for member count in the full screen Map View of Group Messages might appear (e.g. DETAIL_NUMBER_OF_PEOPLE_LABEL). (117287069)

ServiceManagement

Resolved Issues

  • Fixed: Requirements for agents and daemons registered with SMAppService have changed to prevent sandbox escapes. The target executable must be sandboxed if the main app is sandboxed. A small sandboxed trampoline tool can be written to execute scripts and unsandboxed or system tools. (113037504)

StoreKit

New Features

  • New pricing properties price, currency, and currencyCode are now available on Transaction. If an offer was applied to the transaction, a new property offer is available to see information about it (id, type, payment mode), as well as convenience properties offerID, offerType, and offerPaymentMode. (106650768)

Resolved Issues

  • Fixed: The StoreKit 2 Transaction properties price, currency, and Offer.paymentMode now have Optional types. (116592563)

  • Fixed: The StoreKit 2 Transaction properties price, currency, and Offer.paymentMode now have Optional types. (116809380)

  • Fixed an issue causing the refund request “Done” button to not dismiss the sheet when using StoreKit Testing in Xcode. (117482750)

  • Fixed an issue where StoreKit 2 deviceVerification was incorrect, which caused transaction verification to fail. (117689523) (FB13315344)

Swift Charts

Resolved Issues

  • Fixed an issue where a scrollable chart did not respect the initial non-zero binding value passed to chartScrollPosition. (114889276)

SwiftUI

New Features

  • Use _logChanges() to log causes of SwiftUI view updates.

    Call the new debugging method _logChanges() in the body of a SwiftUI view to log information about why the system is updating the view. For example:

         struct MyView: View {
         var body: some View {
             #if DEBUG
             let _ = Self._logChanges()
             #endif
             // … rest of view body …
         }
     }

    As well as the physical property names, “@self” marks that the view value itself has changed, and “@identity” marks that the identity of the view has changed (that is, that the persistent data associated with the view has been recycled for a new instance of the same type).

    The new _logChanges() method is like the existing _printChanges() one, except that the new method uses the system console, which is useful in some debugging workflows.

    Calls to _logChanges() log at the info level to the “com.apple.SwiftUI” subsystem with the category “Changed Body Properties”. (113352555)

Resolved Issues

  • Fixed: Resolved a possible Swift access conflict crash that could occur with toolbar items. (113992797)

  • Fixed: To prevent unintentional implicit dependency cycles, ImageRenderer no longer sends Observable updates when the image it produces changes. This change does not affect the behavior when a dependency is explicitly declared by observing the ImageRenderer’s publisher. (116836341)

WidgetKit

Resolved Issues

  • Fixed: In widgets Text(_:style:) does not animate its content by default. (107582710)
