iPadOSDC: Multiple Windows
summary
Explains how to add true iPad multiple windows by enabling the Info.plist flag and wiring UIScene support, using UIScene and a SceneDelegate to build windows, saving per-window state with NSUserActivity so each scene restores its own detail view, creating new scenes via drag using NSItemProvider and drag & drop, and programmatically closing scenes with requestSceneSessionDestruction. Covers scene lifecycle, when sessions disconnect or are discarded, and how to pick the right scene for notifications and shortcuts.
