Launching your app the swiftui way

" summary

Shows that SwiftUI replaces the old app/scene delegate dance: Xcode 11–13 history, a tiny SwiftUI app that prints lifecycle transitions in the simulator, and a working demo of onChange hooked to scenePhase to observe active/inactive/background. Practical options for SDK init appear: use the App struct init or add a legacy delegate via UIApplicationDelegateAdaptor. Uses Xcode 12/13, Swift, SwiftUI, and the simulator; the demo proves the approach works.
