CNET:

At WWDC 2019 earlier this month, Apple announced Project Catalyst, which streamlines the process for all software makers to bring their own iOS apps to Mac. In an interview with CNET at WWDC, Apple software chief Craig Federighi confirmed that the four iOS apps for Mac released last year will get major updates based on the new technology in Project Catalyst. But he also revealed that the apps will get new designs to make them more Mac-like.

They are not yet in the developer betas but Federighi said they’ll be updated for the public beta.
