# Scenes Manage multiple instances of your app’s UI simultaneously, and direct resources to the appropriate instance of your UI. ## Discussion UIKit manages each instance of your app’s UI using a [`UIWindowScene`](/documentation/UIKit/UIWindowScene) object. A *scene* contains the windows and view controllers for presenting one instance of your UI. Each scene also has a corresponding [`UIWindowSceneDelegate`](/documentation/UIKit/UIWindowSceneDelegate) object, which you use to coordinate interactions between UIKit and your app. Scenes run concurrently with each other, sharing the same memory and app process space. As a result, a single app may have multiple scenes and scene delegate objects active at the same time.  Manage the configuration of new scenes from your [`UIApplicationDelegate`](/documentation/UIKit/UIApplicationDelegate) object. ## Topics ### Essentials [Preparing your UI to run in the foreground](/documentation/UIKit/preparing-your-ui-to-run-in-the-foreground) Configure your app to appear onscreen. [Preparing your UI to run in the background](/documentation/UIKit/preparing-your-ui-to-run-in-the-background) Prepare your app to be suspended. ### Window scenes [Supporting multiple windows on iPad](/documentation/UIKit/supporting-multiple-windows-on-ipad) Support side-by-side instances of your app’s interface and create new windows. [`UIWindowSceneDelegate`](/documentation/UIKit/UIWindowSceneDelegate) Additional methods that you use to manage app-specific tasks occurring in a scene. [`UIWindowScene`](/documentation/UIKit/UIWindowScene) A scene that manages one or more windows for your app. [`UIScene`](/documentation/UIKit/UIScene) An object that represents one instance of your app’s user interface. [`UISceneDelegate`](/documentation/UIKit/UISceneDelegate) The core methods you use to respond to life-cycle events occurring within a scene. ### Configuration [Specifying the scenes your app supports](/documentation/UIKit/specifying-the-scenes-your-app-supports) Tell the system about your app’s scenes, including the objects you use to manage each scene and its initial user interface. [`UISceneConfiguration`](/documentation/UIKit/UISceneConfiguration) Information about the objects and storyboard for UKit to use when creating a particular scene. [`UISceneSession`](/documentation/UIKit/UISceneSession) An object that contains information about one of your app’s scenes. ### Activation and destruction [`UISceneActivationConditions`](/documentation/UIKit/UISceneActivationConditions) The set of conditions that define when UIKit activates the current scene. [`UIScene.ActivationRequestOptions`](/documentation/UIKit/UIScene/ActivationRequestOptions) An object that contains information you want the system to use when activating the session associated with a scene. [`UIWindowSceneDestructionRequestOptions`](/documentation/UIKit/UIWindowSceneDestructionRequestOptions) An object that contains information to use when removing a window scene from your app. [`UISceneDestructionRequestOptions`](/documentation/UIKit/UISceneDestructionRequestOptions) An object you pass to UIKit to permanently remove a scene and its associated session from your app. [`UISceneClosureConfirmation`](/documentation/UIKit/UISceneClosureConfirmation) A configuration specifying a confirmation dialog that will be shown before a user action will result in destruction of the scene session and the disconnection of the scene. ### Scene accessories [`UISceneAccessory`](/documentation/UIKit/UISceneAccessory) A type which can be used to register for a specific type of scene accessory presentation. [`UISceneAccessoryRegistration`](/documentation/UIKit/UISceneAccessoryRegistration) A type which represents the registration for a given scene accessory. ### Scene accessories [Presenting content on a connected display](/documentation/UIKit/presenting-content-on-a-connected-display) Fill connected displays with additional content from your app. [`UISceneAccessory`](/documentation/UIKit/UISceneAccessory) A type which can be used to register for a specific type of scene accessory presentation. [`UISceneAccessoryRegistration`](/documentation/UIKit/UISceneAccessoryRegistration) A type which represents the registration for a given scene accessory. ### URL management [`UIOpenURLContext`](/documentation/UIKit/UIOpenURLContext) A system-provided object that contains the information you need to open a single URL. [`UIScene.OpenExternalURLOptions`](/documentation/UIKit/UIScene/OpenExternalURLOptions) Options you specify when asking a scene to open a URL. ### Errors [`UISceneError.Code`](/documentation/UIKit/UISceneError/Code) Error codes for issues with scenes. [`UISceneError`](/documentation/UIKit/UISceneError) Errors returned during the creation or management of a scene. [`UISceneErrorDomain`](/documentation/UIKit/UISceneErrorDomain) The domain for scene-related errors. --- Copyright © 2026 Apple Inc.
