Always great to see native macOS apps! Is there a reason you aren’t using SwiftUI for the whole thing and that you opted for Core Data instead of Swift Data?
Also, not OP, but I’m glad it’s written in AppKit vs SwiftUI purely; AppKit just feels better on the desktop. I can always “smell” a SwiftUI app just like I can an Electron app.
Unless it's actually SwiftUI taking time to render that UI, which would be bizarre.
As a macOS user I am so used to everything happening in the blink of an eye, so this is something that stands out. It's really not a big problem, 300-400ms.
Was I imagining that wrong?
It’s an AppKit-first app — I’ve used SwiftUI in parts where it fits well, but I’ve avoided relying on it entirely because it’s still maturing, especially on macOS. In certain areas, it can compromise the native look and feel, or introduce unexpected behaviour.
As for Core Data, it’s a proven and robust framework that already does everything I need. Swift Data is still relatively new and doesn’t yet offer the same level of flexibility or stability for more advanced use cases.
Do you write about your experience with macOS dev at all? I would love to hear about it. I still look back fondly on that experience and toss around the idea of revisiting it, Documentation Archive and all.
