In Obj-C, if a property has promised that it conforms to <NSCopying> porotocl and that it would respect copying semantic by being qualified with `@property (copy)`, then we assign a value to `ivar` through the setter by writting down `self.ivar = whatever` in `-init`, accessing would not be direct but via the setter. This behaviour, in fact, doesn't match Obj-C conventions.
