Update/Correction
At ~47min we replaced `@main` with `@UIApplicationMain`, but that wasn't needed. We only had to remove the UISceneSession life-cycle methods from the AppDelegate to make it work.
Background:
On iOS 12 and before, we managed app life-cycle events through the UIApplicationDelegate. On iOS 13, Apple introduced the new UISceneDelegate APIs to respond to life-cycle events occurring within a scene.
New Xcode projects already come configured with an AppDelegate and a SceneDelegate. However, a requirement of this interview challenge was for the app to support iOS 12 and above (and iOS 12 doesn't support UISceneDelegate).
On iOS 12 and before, we had only the UIApplicationDelegate. So the project had duplication in the AppDelegate and SceneDelegate to be able to support both iOS 12 and 13+.
Since this app doesn't require managing scenes, our goal was to remove the UISceneDelegate and use only the UIApplicationDelegate, which works with iOS 12 and iOS 13+. This way, the code works with all iOS versions without duplication or doing more work than needed.
To remove the UISceneDelegate setup, we need to (1) remove the `Application Scene Manifest` entry from the `Info.plist` and (2) remove the UISceneSession life-cycle methods from the AppDelegate. And that's it!

Which tool is used to keep track of notes here?

Hello! That's the default TextEdit Mac app.

I'm going to start applying to jobs very soon. I was wondering if it's totally fine to use dependencies made by me? I don't want to write the same code for each test project I get assigned

Just imagine if it wasn't fine to use your own code. Whether dependencies or not, it's your code! Do make your outlets private, though!

That @UIApplicationMain input from Bogdan was insane ahah

Hi Carlos! Replacing `@main` with `@UIApplicationMain` was actually not needed. Check the video description for more details ✅

Hi Guys, I don't think @UIApplicationMain is required. You might missed to delete the Application Scene Manifest in the target info tab. I never used @UIApplicationMain and it worked for me, Please share your thought.

Hello! We updated the Info.plist ~44min, so it seemed to be required because of the project setup. Our goal was to remove the SceneDelegate and *not* load a Main storyboard on startup ✅

@@EssentialDeveloper ok I tried to follow your steps except to replace @main with @UIApplicationMain, still it's working in XCode 13.4.1. Is there any change Apple have made in XCode version for it? Also how @Main is different from @UIApplicationMain, like for me both are same and work like entry point for the app. However it's possible for multiplatform app UIApplicationMain & NSApplicationMain take care under the Main. Love to understand why @Main didn't work in your case, great if you can share the code version which you were using the time of recoding the session.

Found it! If we remove the SceneDelegate class and entry in the Info.plist, BUT the AppDelegate implements the UISceneSession lifecycle methods, it doesn't work. Removing the UISceneSession lifecycle methods from the AppDelegate made it work (that's what we did at the same time we replaced @main) ✅
