App Entry Point

React Native visionOS uses SwiftUI lifecycle. The app entry point is now App.swift file (by default it is main.m). This change allows us to use full capabilities of the visionOS SDK.

Here is an example from the template:

struct HelloWorldApp: App {
@UIApplicationDelegateAdaptor var delegate: AppDelegate

var body: some Scene {
RCTMainWindow(moduleName: "HelloWorld")

We are using @UIApplicationDelegateAdaptor, a property wrapper that allows us to use familiar AppDelegate in SwiftUI life cycle.

AppDelegate extends RCTAppDelegate which does most of React Native initialization.
