This is using Catalyst, right? UIKeyCommand is a UIKit name, not an AppKit one. And Catalyst doesn't exist prior to Catalina. They've added a whole other (temporary?) operating system. It's perhaps not surprising this has a lot of bugs. Classic wasn't perfect, either.

It’s perhaps surprising that they pushed Catalyst out with so many bugs and unimplemented features. Just look at Apple’s own apps built with it.

On the other hand, it’s not surprising at all. When was the last time Apple cared about quality in MacOS?

I don’t understand why Catalyst exists at all when we have SwiftUI coming soon, which seems much better.

Catalyst lets you run iOS apps on MacOS, and you don’t need to re-write them in SwiftUI.

But I agree with the sentiment.

Twitter is a Catalyst app, yes. Catalyst was used in macOS Mojave for select system apps.
