As far as I can tell, there were no Catalyst sessions<\/a> this year. Apple hasn’t talked about it much since 2021.<\/p>\n\n

The Mac developer page<\/a> says:<\/p>\n

Choose your app-builder technology<\/p>\n

Another early choice to make is which app-builder technology to use for your interface. Apple’s app-builder technologies provide the core infrastructure macOS needs to communicate with your app. They also define the programming model you use to build your interface, handle events, and more.<\/p><\/blockquote>\n

The two technologies listed are SwiftUI and AppKit, with SwiftUI preferred. There is still a navigation bar item for Mac Catalyst<\/a>, but I’m not sure Apple itself is using it much except for the apps like Messages and Home that it already ported. I wonder whether those will become SwiftUI in time. Initially, Catalyst sounded like a transition technology, but, as with Carbon, Apple didn’t paint it that way. Some in the iOS developer community like it<\/a>. It started out with a lot more functionality than SwiftUI. But I don’t hear developers talk about it that much anymore, and Apple doesn’t seem to be using it for new apps. Freeform for Mac uses AppKit and nibs (along with SwiftUI). Journal curiously remains iOS-only.<\/p>\n\n

Catalyst appears to be dead, more-or-less.<\/p>\n<\/blockquote>\n\n

Apple has announced a handful of new features coming to its Journal app this fall, but for reasons only it knows, the company hasn’t announced any plans to bring it to iPad.<\/p><\/blockquote>\n\n

The iOS Journal app improvements look great.<\/p>\n

Still a mystery why it is not available on iPad or Mac.<\/p>\n

Even if it’s just catalyst or otherwise not customized for the other platforms, it would still be incredibly useful as is.<\/p>\n

But instead, I’m going to be using iPhone Mirroring to use the journal app on my Mac. And that just seems so fucking dumb and absurd.<\/p>\n<\/blockquote>\n\n
