Apple announced that the company has no plans to merge iOS and macOS during its Worldwide Developers Conference last year, but it also said it’s working on a way for developers to write apps that work on both operating systems. Project Marzipan, as Apple calls it, wasn’t discussed in much detail at WWDC, but Apple described the News, Stocks, Home, and Voice Memos apps that come with macOS Mojave as examples of Marzipan at work. And we haven’t heard a lot about Marzipan since WWDC.
On Wednesday, Bloomberg’s Mark Gurman reported that Marzipan could be in the spotlight for this year’s WWDC. According to Gurman, Apple could release a software development kit at the conference that will allow iPad developers to port their apps to the Mac. Then, in 2020, Apple will release a kit that ports iPhone apps to the Mac. By 2021, Apple will give developers the ability to create a “single binary” of an app—in other words, one app that can run on Mac, iPad, and iPhone.
