Make your UIKit app work across multiple windows.
Updates UIKit apps to support resizable windows and scene-based lifecycles by replacing legacy shared-state APIs.
When to use it
Use when modernizing Swift or Objective-C UIKit code that relies on shared screen state, interface orientation, application lifecycle, or outdated safe-area assumptions.
Give it a UIKit codebase to modernize; it applies the registered migrations, limited to a subset when explicitly requested.
