As first spotted by Steve Troughton-Smith, release notes for the latest beta build of Xcode include a major development: Mac apps can soon be included as universal purchases with their iPhone and iPad companions.
Universal apps currently enable you to make a single purchase to gain access to both iPhone and iPad versions of an app. Nearly all cross-platform developers default to this option, though some still sell separate iPhone and iPad apps. macOS has never been included as part of universal apps though, even after Mac Catalyst launched last year. That sounds like it’s going to change when the latest OS updates – iOS and iPadOS 13.4 and macOS 10.15.4 – arrive this spring.
This is good news for developers and users alike.
