Ask HN: What it the tech stack of the new WhatsApp desktop?
Uses UIKit.
How to tell if its React Native, SwiftUI or just Cocoa?
- mk89 3y agoTypically I use the activity monitor to analyze the file content. There is always 1 lib at least that a specific framework brings along, even in case of native programs. When that is not enough, you can also get some cues from the Accessibility Inspector to "guess" what a program uses.
- grumblingdev 3y agoMessenger 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.
