The code seems ok to me, I left a couple of questions to understand it better and see whether we can simplify it a little bit.

Also, can we extract lone 24 to 34 into a private function? Something like:

- (UIWindow *)getUIWindowFromScene
{
  // ...moved code...
}

This will make it easier to read the code and to eventually change/remove the code once we don't need all the checks.

What do you think?

React/CoreModules/RCTAlertController.m

React/CoreModules/RCTAlertController.m

+    __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_13_0
+    if (@available(iOS 13.0, *)) {
+      for (UIScene *scene in RCTSharedApplication().connectedScenes) {
+        if (scene.activationState == UISceneActivationStateForegroundActive && [scene isKindOfClass:[UIWindowScene class]]) {


Why the check [scene isKindOfClass:[UIWindowScene class]] is needed? Can scene be of something different from a UIWindowScene class?

For app supports CarPlay, RCTSharedApplication().connectedScenes will include CarPlay scenes such as CPTemplateApplicationScene instance, which may also in active state.
