# UIApplicationPreferredDefaultSceneSessionRole

The preferred initial scene session role for your app.

## Discussion

The system references this key to determine the preferred initial scene session role to create the first scene for your app. If you specify [`UISceneSessionRoleImmersiveSpaceApplication`](/documentation/BundleResources/Information-Property-List/UIApplicationSceneManifest/UISceneConfigurations/UISceneSessionRoleImmersiveSpaceApplication) or [`CPSceneSessionRoleImmersiveSpaceApplication`](/documentation/BundleResources/Information-Property-List/UIApplicationSceneManifest/UISceneConfigurations/CPSceneSessionRoleImmersiveSpaceApplication), the system creates an immersive space scene which connects to your application at launch. To define the style that [`UISceneSessionRoleImmersiveSpaceApplication`](/documentation/BundleResources/Information-Property-List/UIApplicationSceneManifest/UISceneConfigurations/UISceneSessionRoleImmersiveSpaceApplication) uses initially, use the [`UISceneInitialImmersionStyle`](/documentation/BundleResources/Information-Property-List/UIApplicationSceneManifest/UISceneConfigurations/UISceneSessionRoleImmersiveSpaceApplication/UISceneInitialImmersionStyle) key.
