# UIApplicationSupportsMultipleScenes

A Boolean value indicating whether the app supports two or more scenes simultaneously.

## Discussion

Discussion If your app supports multiple scenes, set the value of this key to true. If you set the value to false, UIKit never creates more than one scene for your app. Setting this key to true has implications for your code. An app that supports multiple scenes must coordinate operations to prevent scenes from interfering with each other. For example, if two scenes access the same shared resource, you must synchronize access to that resource using a serial dispatch queue or some other mechanism. Failure to do so may lead to corrupted data or  unexpected behavior from your app.
