Apple wants to combine apps for iPhone, iPad and Mac so all users have the same experience. The company will provide developers with all the necessary tools and allow them to develop one application that will work on all three devices.
The project is codenamed 'Marzipan' and is set to become a major feature on iOS 12 and macOS 10.14 next year. Apple is still working on the project, so the presentation at the World Developers Conference 2018 may be delayed at the last moment.
Apple plans to introduce changes in the next big update iOS as well as macOS. The secret project, codenamed 'Marzipan', will be one of the company's main functions next year. In theory, it can be presented at the 2018 developer conference, if plans do not change.
This solution from Apple will make it easier for developers. They no longer have to create separate programs for macOS and update them regularly. While many developers release desktop versions of their applications, they often lack many features. Moreover, such versions are rarely updated. Apple is not the first company to come up with a generic app. Microsoft tried something similar with Windows Phone and Windows. However, most of these applications turned out to be of poor quality and inconvenient for users.
It is not yet clear if Apple App Store will combine macOS and iOS, but that would certainly make sense.
If the company does not change its plans, the project will be presented at the World Developers Conference 2018, and developers will have time to update their applications using new APIs.
