It’s been rumored that Apple will break up iTunes into its component parts in the upcoming macOS 10.15, with new Music, Video, and Podcast apps to replace the aging iTunes. But apparently, the new standalone Music app will still be built on the bones of iTunes, not a new, Marzipan-based app, according to a report from 9to5Mac.
So instead of building a new Music app from scratch that would draw on a shared codebase with Apple’s existing standalone Music app on iOS (which is built on the UIKit framework), the new Music app for macOS will still be a regular AppKit Mac app. In other words, it’ll probably still basically be iTunes, but with a few more features cut off into separate apps to allow Apple to better focus on music.
