PyObjC BusinessChat Framework

Warnings

• breaking PyObjC dropped support for Python 3.9 in version 12.0 and Python 3.8 in version 11.0. Ensure your Python environment meets the minimum requirement (currently Python 3.10+ for PyObjC 12.x).
  Fix: Upgrade Python to 3.10 or newer, or pin `pyobjc-framework-businesschat` to an older version compatible with your Python (e.g., `<12.0` for Python 3.9).
• breaking PyObjC v11.1 aligned its behavior with `clang`'s Automatic Reference Counting (ARC) documentation for initializer methods. This means methods in the 'init' family now correctly steal a reference to `self` and return a new one. This could subtly change reference counting behavior in complex `__init__`/`__new__` scenarios, potentially leading to memory issues or unexpected object lifetimes.
  Fix: Review custom Python classes that heavily interact with Objective-C initializers, especially those overriding `__new__` or `__init__`, to ensure correct reference management. Thorough testing is recommended.
• gotcha `pyobjc-framework-businesschat` is a wrapper for a macOS-specific framework and will only function on macOS. Attempting to import or use it on other operating systems (e.g., Linux, Windows) will result in an `ImportError` or runtime errors.
  Fix: Ensure your application is deployed and run on macOS. If your code needs to be cross-platform, use platform checks (`sys.platform == 'darwin'`) to conditionally execute PyObjC-related code.
• gotcha In PyObjC 10.3, the ability to use `__init__` was removed when a class or its superclasses provided a user implementation of `__new__`. While this was partially reverted in 10.3.1 to allow `__init__` when `__new__` is user-implemented, code relying on `__new__` provided by PyObjC still cannot use `__init__` as before 10.3.
  Fix: If your Python classes using PyObjC override `__new__`, exercise caution with `__init__` and test thoroughly. Avoid calling `__init__` if `__new__` is inherited from `objc.objc_object` or another PyObjC internal mechanism.

Install

Imports

• BCAuthenticationManager

  from BusinessChat import BCAuthenticationManager

Quickstart

This example demonstrates how to import a key class from the BusinessChat framework and check if the Business Chat service is supported on the current macOS system. It includes a platform check for safe execution.

import objc
import sys

if sys.platform == 'darwin':
    try:
        from BusinessChat import BCAuthenticationManager
        print(f"BusinessChat framework imported successfully. Class: {BCAuthenticationManager}")
        # Check if Business Chat is supported on the current system
        if BCAuthenticationManager.sharedAuthenticationManager().isSupported():
            print("Business Chat is supported on this macOS system.")
        else:
            print("Business Chat is NOT supported on this macOS system.")
    except ImportError:
        print("BusinessChat framework is not available. Ensure you are on a compatible macOS version.")
    except Exception as e:
        print(f"An unexpected error occurred: {e}")
else:
    print("This quickstart requires macOS to run PyObjC BusinessChat framework.")
