The new Xcode 11.4 beta update, released today alongside the iOS 13.4, tvOS 13.4 and macOS Catalina 10.15.4 betas, includes support for universal purchases, allowing developers to bundle iOS apps, tvOS apps, and Mac apps together for one purchase price.
This will allow developers who make a Mac app and an iOS app to sell them in a single bundle, something that has not previously been possible.
Starting in March 2020, you’ll be able to distribute iOS, iPadOS, macOS, and tvOS versions of your app as a universal purchase, allowing customers to enjoy your app and in‑app purchases across platforms by purchasing only once. You can choose to create a new app for these platforms using a single app record in App Store Connect or add platforms to your existing app record. Get started by building and testing your apps using a single bundle ID with Xcode 11.4 beta.
