Patents are about how you do something, not what you do. This patent is about how Apple's compiler implements some programing language features. It does not protect the programming language feature itself. Another compiler that employs a different 'how' can implement the same programming feature. So, if you don't want to infringe on this patent, you are forced to invent (or use) another way of doing the same thing.
