I'm looking forward to when you can just build an app once and use it across iOS and Mac right out of the box. Catalyst seems like a good first step in that direction.

SwiftUI universal apps do this even better by automatically using the appropriate backing controls for the targeted platform — e.g. a SwiftUI `Button` translates to `NSButton` on macOS and `UIButton` on iOS.

I think it's ultimately what Apple intends to make the flagship way to develop on their platforms. Catalyst exists mostly as a way to pull existing iOS apps and iOS developers under the Mac umbrella.

Yes. Catalyst is a kinda-clever but janky solution. It basically puts the iPad simulator on the screen.
