objc-cffi

A CFFI-based library for accessing the Objective-C runtime. This library is meant for use in Pythonista and requires Python 3.5 and CFFI 1.8 or later.

Features

• Calling methods on Objective-C classes and objects using Python method call syntax
• Getting and setting Objective-C properties using Python attribute syntax
• Checking types of Objective-C objects using isinstance and issubclass
• Easy use of Objective-C classes and protocols using the objc.classes and objc.protocols pseudo-modules
• Automatic deduction of method signatures and property types from type encodings
• Automatic conversion of Python to Objective-C objects when passed to methods
• Conversion from and to most objc_util objects
• Hiding of private and known deprecated methods in dir lists, for clean autocompletion in the interactive Python console
• Access to class, protocol, method, property, and ivar metadata

Issues and missing features

• Subscript syntax for Objective-C collections
• Python iteration support for Objective-C collections and fast enumerations
• Creation of custom Objective-C classes at runtime
• Better struct support (methods taking or returning structs currently require manual setting of restype or argtypes to be properly usable)
• Performance optimizations (this library is quite slow compared to objc_util)
