The WWDC 2019 had a major impact on the UI toolkit landscape: while the venerable AppKit APIs remained available, Apple removed the old Carbon APIs and introduced 2 brand new frameworks: Mac Catalyst and SwiftUI. Apple sporadically mentioned some apps built with these new UI toolkits. In this article, I try to bring a better overview of Apple’s use of AppKit, Mac Catalyst and SwiftUI in the different versions of macOS, from macOS Mojave to macOS Ventura. Really great visualisation, and shows that the march to SwiftUI continues – however, I’m not entirely sure macOS users should be happy about that.
