App protocol looks simpler but is decisive for your applications' structure and organization.
This sketch note shares a general look at the parts involved while implementing your app's entry point.
Things to take in mind:
App protocol represents structure and behavior.
body is the content and can define scenes.
Scene acts as the root view of the view hierarchy and can be more than one.
@main initialize and call the
main() method which runs your app.
init() runs by default.
6. You can have multiple scenes whose lifecycles will be managed by the system.
I hope this sketch note is helpful to you.

Great sketch note! The SwiftUI App protocol is indeed a crucial component in organizing and structuring SwiftUI applications. As you have pointed out, it may seem simpler than other aspects of the framework, but it plays a decisive role in ensuring a well-organized and scalable app.
It's worth noting that we use the SwiftUI App protocol for various tasks, such as initializing the app, setting up the app's lifecycle, managing the app's state, and defining the app's views and window hierarchy. Overall, this sketch note is a helpful reminder of the importance of the SwiftUI App protocol and how it contributes to building robust and maintainable SwiftUI applications.
