With macOS Mojave, Apple introduced four apps that were previously only available on iOS: Stocks, News, Home and Voice Memos. During the presentation, speculation began on how these could be the iOS apps themselves, ported to the Mac with the rumored Marzipan project. At the end of the Keynote, Craig Federighi presented a sneak peek at a multi-phase project they’ve been working on. Without giving it any name, Craig explained that this project allows iOS apps to be ported to the Mac with minimal effort,that Apple used this for their News, Stocks and Voice Memos apps and that it would become available to third-party developers next year. I decided to explore this project and see just how minimal an effort it would be to port an existing, real-world iOS app to the Mac.
