i pattern nested private class in objective c. requirements are: class not visible/accessible other classes. class can execute methods (i.e., not c struct) containing class members visible/accessible nested class considering comments, simplifying requirements: inner class may accessible other classes, not visible (similar using category hide private methods). inner class not have nested is still not possible? objective-c has no notion of private classes or private instance variables in formal declarative fashion. instead, visibility in objective-c entirely controlled declare something. if in header file, can imported else. if declared in implementation file, cannot (reasonably) imported and, therefore, private compilation unit. and "it", mean pretty can declared; class, global, etc... i.e. if stick @interface/@implementation pair class in .m file, class private compilation unit. of course, without namespaces, make sure class uniquely ...
