depth42/PWViewController
PWViewController replaces NSViewController which under Mac OS 10.7 and ARC has the limitation that instances cannot not be referenced by a weak property. As view controllers often take the role of a delegate this is a very painful limitation. PWViewController is a simple re-implementation of NSViewController for ARC with some additional features, like a disposal mechanism and debug-mode instance count which lets leaking view controller instances turn up in unit tests.
