The launch screen is a user interface file that runs while your iOS app is launching. The launch screen file uses a subset of the UIKit views and will support multiple aspect ratios and multi-tasking modes. To create a launch screen file, edit the default launch screen file, called LaunchScreen.storyboard, that Xcode adds to your project. If you have an older project, you can add a launch screen file and set the launch screen file for the target in the project editor. For how to design a launch screen, read Launch Screen in Human Interface Guidelines.
Alternatively, you can use an asset catalog for a launch image.
