At Apple’s Worldwide Developer Conference (WWDC), executives unveiled the much-anticipated Project Catalyst, a new platform that allows developers to more easily bring their iOS apps developed for the iPad over to Macs.

Project Catalyst—formerly code-named Project Marzipan—makes it easier for iOS developers who want to bring their apps to more than 100 million active Mac users with the latest version of macOS, Catalina. With Catalyst, development team can build one app that can span from iPhone to iPad to Mac, Craig Federighi, Apple’s senior vice president of software engineering, said during the keynote. This opens up more possibilities for integrated app support across the Apple ecosystem.
