Things are about to get a lot easier for iDevelopers in the coming years: Apple is currently working on a new software development kit allowing coders to create a single app that works on the iPhone, iPad, and Mac (alternate source sans paywall). The initiative, dubbed “Marzipan,” will be fully realized by 2021: “developers won’t have to submit their work to different Apple App Stores, allowing iOS apps to be downloaded directly from Mac computers -- effectively combining the stores.” The work coincides with the company’s preparations to merge more of the underpinnings of its hardware. Currently, iPhones and iPads are powered by Apple processors, while Macs use Intel Corp. chips. Apple plans to start transitioning some Macs to its own chips as early as 2020, Bloomberg News reported last year. Despite the app merger plan, Apple has said it won’t combine iOS and macOS into a single operating system.
