As other people is saying, the arguments from the article point Apple to be robust, not antifragile. As it still has many single points of failure in its design the whole thing may still break by a hardware bug, or the lack of software or whatever. In order to be antifragile it should become stronger after each stressor is applied, but we can only see it becoming stronger by the stressors over the competitors not onto itself. Still apples strategy is very good, but not as antifragile as something like a Linux OS which by not having hardware and being crossplatform may still grow market and show strength from such lack of hardware vendors.
