It’s now possible for developers to make their apps available as a universal purchase. Apple enabled the change on Monday, paving the way for macOS, iOS, tvOS, and watchOS apps to be bundled as one.

Apple is not forcing developers to use universal purchases. It does hope, however, that the move will promote the use of Catalyst for porting iPad apps over to Mac.

Apple seeded the second beta build of iOS 13.4 and iPadOS 13.4 to developers this morning bringing a bunch of bug fixes and some small new features to the iPhone and iPad.

Included among the changes are some more changes to the controversial toolbar in the Mail app. Apple also added some under-the-hood improvements and some changes to how location authorization works in apps.

Apple is laying the groundwork to make it easier for developers to distribute their apps across all of Apple’s platforms.

Included in Wednesday’s big batch of beta updates, Apple introduced a new option in Xcode 11.4 beta 1 for developers to build and test apps using a single bundle ID. Starting in March, iPhone users will be able to download an app via the iOS App Store and then (if the developer supports it) download it on other Apple platforms with ease.

This simple change might seem like an obvious added convenience for users, but it also sets up the App Store for some colossal changes over the next few years. It will force Apple developers to make some big decisions about their businesses.
