[Pyobjc-dev] PyObjC 3.2 released

[Ronald O. <ron...@ma...>]

Hi,

I’ve pushed PyObjC 3.2 to PyPI (finally…). The major new feature in this version is support for OSX 10.12 (Sierra) and the new APIs introduced in this version of OSX.

There is also a backward incompatible change: the default method signature is calculated differently than before. This will primarily affect code that adds python-only method to a class, like so:

   class MyObject (NSObject):
        def amethod(self, a, b): pass

This would work in previous versions, but no longer works because the method name suggests that this is a method without arguments (the translation to an Objective-C selector contains no colons). The workaround for this is easy enough: use the decorator “objc.python_method” on methods that won’t be called from Objective-C.

This change was necessary to make it possible to use generic decorators on selectors.
