Bloomberg's Mark Gurman, who has reported on Apple's "Marzipan" project to unite the application platforms for Mac and iOS for many years, has a new report today describing the scheduled timeline of the bet:
Later this year, Apple plans to let developers send iPad apps to Macs through a new software development set that the company will release as early as June at its annual developer conference. Developers will still have to submit separate versions of the app to Apple's iOS and Mac App Stores, but the new set means they don't have to write the underlying software code twice, the people knew about the plan.
By 2020, Apple plans to expand the set so that iPhone applications can be converted to Mac apps in the same way. Apple engineers have found this challenging because iPhone monitors are so much smaller than Mac computer monitors.
By 2021, developers will be able to merge iPhone, iPad and Mac applications into an app or what is called a single binary. "This means that developers don't have to submit their work to various Apple App Stores, so iOS apps can be downloaded directly from Macs, effectively combining the stores.
All this makes perfect sense – that iPad apps are easiest to convert to mac, as iphone apps will follow, and finally, the goal is to allow developers to generate a single binary that will run on any device Apple does.
Apple has said several times that Mac and iOS can't merge, but since last year's WWDC it has been clear that the overall goal is to provide a common app platform over the operating systems. to run traditional Mac applications that have more features than iOS apps do.)[Read on Six Colors.]
