PyObjC Files

• Drop support for Python 3.9, which will go out of support before PyObjC 3.12 is released.

• Added AVFAudio as a separate toplevel package, instead of keeping it merged in into AVFoundation.

The package is included in the pyobjc-framework-AVFoundation distribution.

• Updated metadata for the macOS 26 SDK.

As part of this introduce bindings for the following new framework bindings:

• ARKit
• CompositorServices
• GameSave

There are no bindings for the MetalPerformancePrimitives at this time, it is a low-level C++ library that would require a lot of work to create bindings.

• In macOS 26 a number of type encodings for block arguments include a signature for the block interface. Update PyObjC runtime introspection to ignore that information.

• Dropped old metadata scans. That is, all framework bindings are now created from the most recent macOS SDK headers with some manual additions and annotations.

This change required adding manual entries for, in particular, constants that were renamed in by now old versions of macOS and have been removed from Apple's headers by now. These will be removed from PyObjC in a future update as well (but after a transition period where using them will raise a warning).

This has the following user visible side effects (as far as they are visible, most of the the changes below affect versions of macOS that are long gone):

• Accounts: The following constants are no longer available (on the old versions of macOS where these were available): ACFacebookAppVersionKey, ACFacebookPermissionGroupKey, ACFacebookPermissionGroupRead, ACFacebookPermissionGroupReadWrite, and ACFacebookPermissionGroupWrite.

• AppKit: The NSFileWrapper class no longer supports with keyword arguments path, and serializedRepresentation, and the keyword set (URL, options, error).

• AuthenticationServices: The classes ASAccountAuthenticationModificationReplacePasswordWithSignInWithAppleRequest and ASAccountAuthenticationModificationUpgradePasswordToStrongPasswordRequest no longer have a keyword argument set named (user, serviceIdentifier).

• Automator: class AMBundleAction no longer accepts the keyword set (definition, fromArchive).

• CFNetwork: The following functions were deprecated before macOS 10.6 and were removed in the macOS 10.15 SDK: CFHTTPReadStreamSetRedirectsAutomatically, and CFNetServiceSetProtocolSpecificInformation.

• CloudKit: CKDiscoverUserInfosOperation no longer recognizes the keyword set (emailAddresses, userRecordIDs). CKFetchDatabaseChangesOperation no longer recognizes the keyword argument previousServerChangeToken. CKShare no longer recognizes the keyword arguments recordZoneID, rootRecord, and the keyword set (rootRecord, shareID). CKSubscription no longer recognizes the keyword argument coder, and the keyword sets (recordType, predicate, options), (recordType, predicate, subscriptionID, options), (zoneID, options) and zoneID, subscriptionID, options).

• CoreAudio: The following functions are no longer available (all were deprecated between macOS 10.5 and 10.8, and removed from the macOS 10.15 SDK): AudioHardwareClaimAudioDeviceID, AudioHardwareDevicesDied, AudioHardwareDevicePropertyChanged, AudioHardwareDevicesCreated, AudioObjectCreate, AudioHardwareStreamPropertyChanged, AudioHardwareClaimAudioStreamID, AudioObjectPropertiesChanged, AudioHardwareStreamsCreated, AudioObjectsPublishedAndDied, AudioHardwareStreamsDied.

  The following constants are no longer available because they are not useful in python code: CA_PREFER_FIXED_POINT and COREAUDIOTYPES_VERSION.

• CoreData: The constant NSFetchRequestExpressionType is no longer available.

• CoreLocation: CLBeaconIdentityConstraint no longer supports the keyword UUID and the keyword sets (UUID, major) and (UUID, major, minor).

• CoreServices: The following functions are no longer available (all were removed in the macOS 10.7 SDK): LSInit and LSTerm.

• CoreText: The constant kCTVersionNumber10_6_7 is no longer available.

• CryptoTokenKit: The following constants are no longer available. Use the modern names instead: TKSmartCardNoSlot, TKSmartCardSlotEmpty, TKSmartCardSlotProbing, TKSmartCardSlotMuteCard, and TKSmartCardSlotValidCard.

• DiscRecording: The following constants are no longer available: DRCDTextEncodingASCII, kDRCDTextEncodingASCII, DRCDTextEncodingISOLatin1Modified, and kDRCDTextEncodingISOLatin1Modified.

• DiskArbitration: The following constants are no longer available: kDADiskOptionEjectUponLogout, kDADiskOptionMountAutomatic, kDADiskOptionMountAutomaticNoDefer, and kDADiskOptionPrivate.

• GameController: The struct type registration GCExtendedGamepadValueChangedHandler is gone (the existence of this type was a bug).

• ImageCaptureCore: Constant ICCameraDeviceSupportsFastPTP is no longer available (only affects macOS 10.11).

• Intents: Removed constant INMessageReactionTypeEmojiReaction, use INMessageReactionTypeEmoji instead.

• Intents: INAggregatedMessageReaction no longer accepts the keyword set reactionType, emoji, reactionCount). INMessage no longer accepts the keyword sets (identifier, conversationIdentifier, content, dateSent, sender, recipients, groupName, serviceName, messageType, referencedMessage, reaction, aggregatedReactions) and (identifier, conversationIdentifier, content, dateSent, sender, recipients, groupName, serviceName, messageType, referencedMessage, sticker, reaction, aggregatedReactions). It does accept these keyword sets without the aggregatedReactions keyword though.

• Intents: The INColor class no longer accepts the keyword set (read, green, blue).

• Intents: The INHeadUnit class no longer accepts the keyword set (bluetoothIdentifier, iap2Identifier).

• Intents: The INMediaSearch class no longer accepts the keyword set (mediaType, sortOrder, mediaName, artistName, albumName, genreNames, moodNames, activityNames, releaseDate, reference, mediaIdentifier).

• MLCompute: Class MLCOptimizer no longer has a keyword argument named descriptor.

• PassKit: The following constants are no longer available: PKDisbursementRequestScheduleFuture and PKDisbursementRequestScheduleOneTime.

  Because of this the type PKDisbursementRequestSchedule has been removed as well.

  The metadata for PKDisbursementAuthorizationController has been removed.

  Class PKShareablePassMetadataPreview no longer accepts the keyword set (passThumbnail, localizedDescription).

• PubSub: Class PSFeed no longer accepts the keyword URL and the keyword set (data, URL).

  Note that the entire framework was removed in macOS 10.15, and the Python bindings will be removed in PyObjC 13 at the latest.

• Quartz: The following constants are no longer available: CGFLOAT_EPSILON, CA_TEST, CA_TESTABLE_CLASS, CA_TESTABLE, kCGErrorLast.

• Quartz: The following structs are no longer available (all of them contain callback pointers which aren't used in PyObjC's bindings for the APIs that use those structs): CGFunctionCallbacks, CGDataProviderCallbacks, CGPatternCallbacks, CGDataConsumerCallbacks, CGDataProviderDirectAccessCallbacks, CGDataProviderSequentialCallbacks, and CGPSConverterCallbacks.

  These methods were in a beta version of the macOS 11 SDK, but are no longer present in SDKs.

• WebKit: A number of informal protocol definitions were removed. This should not affect using the library: WebUIDelegate, WebViewEditingDelegate, WebPolicyDelegate, WebDownloadDelegate, WebResourceLoadDelegate, WebFrameLoadDelegate, and WebJavaPlugIn.

• Added objc.NSInteger, objc.NSUInteger and objc.CGFloat that will make it easier to use type annotations that match Apple's type information.

• Fix edge cases in method accessors when some uses of SomeClass.pyobjc_instanceMethods.method would result in a method object that's bound to a meta class.

• Fix memory leak due to incorrect reference count handling in looking up metadata.

• Fix edge case in handling registration of multiple custom helpers to call a selector.
