Crash in interfaceOrientationDidChange when using SceneDelegate (Xcode 26)

[TeunVR]

Description

When using Xcode 26 a warning is shown that UIScene lifecycle must be supported:
UIScene lifecycle will soon be required. Failure to adopt will result in an assert in the future.

I added a SceneDelegate that uses the RCTReactNativeFactory to start React Native.
However there are parts in React Native that still expect a window property on the AppDelegate.

For example in RCTDeviceInfo.interfaceOrientationDidChange:
BOOL isRunningInFullScreen = CGRectEqualToRect(application.delegate.window.frame, application.delegate.window.screen.bounds);

Steps to reproduce

Note: Use Xcode 26.

1. Launch the reproducer app on ios simulator or device
2. Press home button to background the app
3. Rotate the device
4. Foreground the app again: crash

Warning

Missing reproducer: We could not detect a reproducible example in your issue report. Reproducers are mandatory and we can accept only one of those as a valid reproducer:

• For majority of bugs: send us a Pull Request with the RNTesterPlayground.js edited to reproduce your bug.
• If your bug is UI related: a Snack
• If your bug is build/upgrade related: a project using our Reproducer Template

You can read more about about it on our website: How to report a bug.

The reproducer is not missing. It just fails to build because Xcode26 is needed.

[atulgpt17]

I am able to repro this issue in the provided project. Though it has some custom changes related to iOS.

[TeunVR]

Yes that is correct. I modified the AppDelegate and added SceneDelegate since most AppDelegate lifecycle callbacks will (soon) be deprecated:
https://developer.apple.com/documentation/Technotes/tn3187-Migrating-to-the-UIKit-scene-based-life-cycle

This change is probably much bigger than just this crash. Also AppState: https://github.com/facebook/react-native/blob/02e3a999ed1c59b4dc0d5f925af94c0c5b117d57/packages/react-native/React/CoreModules/RCTAppState.mm#L8
