v10.0

• Update bindings for macOS 14

  Symbols newly introduced in macOS 14 were added to the existing bindings,
  and the following new bindings were introduced:

  • Cinematic

  • MediaExtension

  • SensitiveContentAnalysis

  • Symbols

• The "IMServicePlugIn" bindings are no longer available

  The entire framework was deprecated in macOS 10.13 and removed in macOS 14.
  The bindings can not be build using the latest SDK, and had (at best) limited
  use.

• #542: PyObjC 10 requires Python 3.8 and no longer supports Python 3.7

• #547: Removed all MAC_OS_X_VERSION* constants from objc.

  These constants are needed in practice (switch to :func:objc.available to
  check for platform availability), and caused unnecessary code churn.

• The value for objc.options.deprecation_warnings is now a string
  instead of an integer.

• #555: Fix unintended incompatibility with pytest in PyObjCTools.TestSupport

• #295: The lazy loading machinery by default no longer uses
  objc.ObjCLazyModule, but uses module level __dir__ and
  __getattr__ instead. The class :class:objc.ObjCLazyModule is still
  available, but is deprecated

  As a side effect of this objc is no longer an attribute of framework
  binding packages (e.g Foundation.objc is no longer a valid attribute).

  Another side effect of this is that all attributes added by the import system
  are now correctly present in the packages for framework bindings.

  And a final side effect is that private symbols (prefixed with underscore) are
  no longer imported from dependencies of framework bindings (more closely matching
  the from dependency import * behaviour that the lazy importer emulates.

• Add attribute __framework_identifier__ to all framework bindings with the
  identifier of the corresponding system framework.

• #295: Introduce :func:objc.createFrameworkDirAndGetattr to
  create module level __dir__ and __getattr__ for use by
  framework bindings.

• #561: Tests now validate the bundle identifier value used in framework bindings.

  This resulted in a number of changes to framework bindings with incorrect
  bundle identifier values. This shouldn't affect user code because the
  bundle loader falls back on the framework path when the identifier cannot be found.

• #559: Avoid test failures in pyobjc-core when pyobjc-framework-Quartz is
  not installed.

• A number of classes can no longer be subclasses in Python because they are marked as non-subclassable
  in the macOS 14 SDK (either directly or as "subclassing is deprecated":

• The encoding of a number of basic types changes, in particular those
  of CoreFoundation struct types and SIMD struct types. None of this
  should affect user code.

• objc.getClassList now has an optional positional argument to
  ignore classes with a name that aren't identifiers.

• Some of the functionality in CoreFoundation was rewritten in Swift
  in macOS 14, with Swift subclasses of NSArray and NSDictionary.
  Those classes break an invariant of PyObjC: the superclass of the root
  of the Swift class hierarchy changes when the class is instantiated
  for the first time (from NSObject to the correct superclass).

  PyObjC 10 contains a workaround for this by ignoring these classes
  unless they are needed to create a proxy for an instance (FB12286520).

• Fix crash when the method signature retrieved from the Objective-C runtime
  contains the class name for a method returning id.

• Remove old 32-bit support in metadata override files.

• Restructure objc.simd: The matrix types are now named simd_float3x3
  instead of matrix_float3x3, with the older name as an alias (to match
  older system headers).

• Fix crash when loading the libdispatch bindings on recent macOS versions
  (at least macOS 13, possibly earlier)

• dispatch.dispatch_source_t is renamed to dispatch.dispatch_source_type_t
  to match the type name in C code.

• #569: Xcode 15 has a bug when using weak symbols and targeting older macOS
  versions. Switch to the old linker when detecting Xcode 15.
