I'd be happy to discuss! My first all-swift project. Was pretty rough at first, but Apple's done a great job of iterating on it. 100% AppKit, though. SwiftUI looks super cool, but it's just too new for me to feel confident relying on it. Plus, we currently support 10.14 as well.

thanks for replying! the app looks totally awesome. i was asking my question because i have been gathering resources for learning swift but from time to time i would read things like it's not mature enough with some macOS frameworks and you have to use objective-c. these comments and the fact that the language itself kept changing/evolving are often off-putting. but i think this just renewed my interest!

Thank you so much!

I think Swift is there now. There were some very painful migrations, but for the past 2-3 years it has been different. It is true that it's a real pain to use some C-based APIs with it, but those are pretty rare. And, often you can find a Swift wrapper for them if you really need to. I've been using ObjC for 25 years, but I'm now pretty into Swift. I'd go for it.

You should be fine using all swift now. The only thing is there are FAR more resources for learning Swift in an iOS context out there then macOS and you may have to figure some things out on your own.

There are very few APIs that cannot be used from Swift. I can't even think of any off the top of my head.
