Apple’s rumored combined code base, which was said to debut at the Worldwide Developer Conference this year, may be most likely to arrive in 2019.
The project, codenamed “Marzipan”, is thought to function as a hybrid macOS/iOS app platform, wherein it’s been thought that developers could write both macOS and iOS apps as a single bundle, sharing a unified code base between the two operating systems.
Per John Gruber of Daring Fireball, it may have been Apple’s plan all along has been to roll this out with macOS 10.15 and iOS 13, which puts the target release in 2019.
As such, there may not be any word on the project at next month’s WWDC event.
That being said, 2019 may be the year macOS goes 64-bit only, dropping support for all 32-bit apps. iOS has already made the transition, so if developers are working with these rumored APIs it makes sense for macOS to follow suit in 2019.
Stay tuned for additional details as they become available.
