react-native: [iOS][KeyboardAvoidingView] Using KeyboardAvoidingView inside a ScrollView causes the app the crash when focusing an input

Description

When KeyboardAvoidingView inside a ScrollView and focus a TextInput the app crashes (goes extremely slow).

This seems to only happen if the KeyboardAvoidingView needs to trigger the animation, if the ScrollView is small it works fine.

Testing with react native 0.72.9 the issue doesn’t seem to happen

Steps to reproduce

  1. install the app yarn ios
  2. Using the simulator make sure the keyboard shows when entering a text input
  3. Focus a text input and start typing on the keyboard
  4. Dismiss the keyboard / click outside of the input
  5. You will notice the app has now hung

@cortinico same issue.

Moving KeyboardAvoidingView over a ScrollView fixed my problem with crashing application when clicking on an input (IOS)

The crash was happening when publishing the app and on real device.

Guideline 2.1 - Performance - App Completeness

We discovered one or more bugs in your app. Specifically, login screen was unresponsive. Please review the details below and complete the next steps.

Review device details:

  • Device type: iPad Air (5th generation)
  • OS version: iOS 17.3.1

We were running into this as well and have temporarily removed the KeyboardAvoidingView that was triggering this.

Like @kokosky93 , my workaround was to swap the component order to make the KeyboardAvoidingView the parent element of the ScrollView, then add a new child View for applying container styles that were previously on the KeyboardAvoidingView.

So far, everything seems to be working as intended.

I also observed that this issue only affected distributions running on real iOS devices. Not reproducible in either ExpoGo or Android builds.
