What it the tech stack of the new WhatsApp desktop?


Uses UIKit.

How to tell if its React Native, SwiftUI or just Cocoa?

Messenger seems to be React Native evident by RCTView everywhere. It also uses NSView instead of UIView.

WhatsApp seems to use UIView, but I couldn't find evidence of SwiftUI, so am assuming its just a UIKit app.

There are some very similar UI components to the mobile app, so I am guessing they want to unify as much as they can between the two codebases.

WhatsApp Windows seems to be a native Windows app.
