# Scenes

Manage multiple instances of your app’s UI simultaneously, and direct resources to the appropriate instance of your UI.

## Overview

Overview UIKit manages each instance of your app’s UI using a UIWindowScene object. A scene contains the windows and view controllers for presenting one instance of your UI. Each scene also has a corresponding 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 object.
