Feedback: SwiftUI app lifecycle: issues with ScenePhase and using AppDelegate adaptors

[dennisbirch]

1. I'm glad to see I'm not the only one experiencing this apparent oversight

2. "Unexpectedly, the main view receives onAppear() before your app receives the scene phase change. In the sample above, that would be ContentView. That’s like receiving viewWillAppear() on your root view controller before application(_:didFinishLaunchingWithOptions:) gets called."

This is exactly the behavior I ran across when trying to translate my iOS (UIKit) experience to a macOS (AppKit) project. I couldn't understand why nothing was being set up properly in my main view until I realized that viewWillAppear was being called in the ViewController before the AppDelegate's didFinishLaunching... method was called.
