dismissKeyboard searched for the first responder from [UIApplication sharedApplication].delegate.window, which apps on the UIKit scene life cycle (React Native 0.88 template, Expo SDK 58) do not have, so it threw '-[AppDelegate window]: unrecognized selector'. Start from RCTKeyWindow() instead.

dismissKeyboardinRCTCustomInputControllerTemp.mlooks for the first responder starting from[UIApplication sharedApplication].delegate.window.With the UIKit scene life cycle the window belongs to the scene delegate and the AppDelegate has no
windowproperty. That is the React Native 0.88 template, and Expo SDK 58 (SDK 57 withenableSceneSupport). Apple requires the scene life cycle for apps built with the iOS 27 SDK (TN3187), and App Store uploads need that SDK from April 2027. In such an app,dismissKeyboardthrows:This starts the search from
RCTKeyWindow()(<React/RCTUtils.h>), which returns the same window on the classic life cycle and the scene's key window otherwise. It's the onlydelegate.windowuse I found in the package.Testing: I reproduced this crash pattern, and confirmed the same fix, with two other libraries on a fresh React Native 0.88.0-rc.4 app in the iOS simulator (react-native-blob-util#498, invertase/react-native-google-mobile-ads#911, the latter now approved). I have not run the ui-lib demo app.
Found while adding a UIScene check to NativeKeel, a React Native health-check CLI I maintain.
