You obviously didn't pay attention to what I wrote. I paid great attention to both WWDCs. In fact I read the Swift book immediately after the announcement. However, the point I am making remains true: Obj-C isn't going away soon and the linked article is not about Swift pulling away from Obj-C (indeed, it's about Swift catching up to Obj-C -- see author's comment elsewhere in thread). In fact, here's a link to an article explaining how to bridge from Swift to Obj-C to make use of simd.h. https://www.safaribooksonline.com/library/view/learning-swifttm-programming/9780133950410/ch11lev1sec5.html https://www.safaribooksonline.com/library/view/learning-swif...
