Apple may have only introduced 64-bit computing to iPhones and iPads a little over a year ago, but it’s already preparing for the day when legacy 32-bit code is gone for good. The Cupertino crew is now telling developers that their iOS apps must include 64-bit support from February 1st onward. While the company won’t kick out existing titles, both new apps and updated releases will have to make the switch. Theoretically, this is easy — developers just have to build apps using the most recent tools and standard settings.
