[CRASH] Swiping left/right using ReanimatedSwipeable causes immediate crash on iOS

[PrivioSupport]

Description

After upgrading my Expo project to SDK 54, importing and rendering causes an immediate crash on iOS, even with a minimal setup. (Expo SDK 54 / RN 0.81.4 / RNGH 2.28.0 / Reanimated 4.1.0)
Note that i'm in bare workflow.

Here's what happens :

Enregistrement_de_lecran_2025-09-23_a_14.43.28.mov

The crash occurs as soon as we swipe.
It does not reach the render stage.

I haven’t tested Android yet.

Steps to reproduce

Upgrade to Expo SDK 54

Install dependencies with expo install

Copy this minimal exemple

import ReanimatedSwipeable from "react-native-gesture-handler/ReanimatedSwipeable";

const App = () => {
        return (
            <ReanimatedSwipeable>
                <Text style={{ color: "white" }}>Hi ! Swipe me and it'll crash !</Text>
            </ReanimatedSwipeable>
        );
    }

Build and install in Bare mode and swipe the item to the left/right, it'll crash.

A link to a Gist, an Expo Snack or a link to a repository based on this template that reproduces the bug.

Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?

[nickplee]

Seeing the same.

[Mattis44]

+1, seems related to a mismatch of RN-Reanimated and RN-Gesture-Handler.
Just seeing lot of deprecated funcs used in node_modules for ReanimatedSwipeable from gesture-handler such as runOnJs() from RN-Reanimated.

This mismatch seems happen when you npx expo install --fix

[Mattis44]

just saw that gesture-handler isn't available for RN 0.81 #3643

[migueldv90]

I'm having the same issue. I work for web but not for native(iOS).

[Mattis44]

Just saw this cherry pick (#3688) merged to @next, is it possible to install the @next version from npm such as npm i react-native-gesture-handled@next ?

[latekvo]

Hi, I tested this issue on a fresh expo app, using the repro you provided, and did not observe any crash.

Tested on:

• expo 54.0.10
• react-native 0.81.4
• react-native-gesture-handler 2.28.0
• react-native-reanimated 4.1.0

With physical iPhones with:

• iOS 26.0
• iOS 18.6.2

Would you please be able to submit a full reproducer app? The code snippet you provided alone does not seem to reproduce this issue.

[PrivioSupport]

Made the reproduction and i had the bug, the crash appeared after made changes to the babel.config.js, thats the only thing i know

https://github.com/PrivioSupport/rn-reanimated-gesture-repro

Made this with npx create-expo-app reanimated-swipeable-repro -t bare-minimum

[PrivioSupport]

Prev babel.config :

module.exports = function(api) {
  api.cache(true);
  return {
    presets: ['babel-preset-expo'],
    plugins: ['react-native-reanimated/plugin'],
  };
};

the crash appear with this config :

module.exports = function (api) {
  api.cache(true);

  return {
    presets: [
      [
        "babel-preset-expo",
      ],
    ],
    plugins: [
      [
        "module-resolver",
        {
          root: ["./"],
          alias: {
            "@": "./",
          },
        },
      ],
      "react-native-worklets/plugin",
    ],
  };
};

[latekvo]

@PrivioSupport the reproducer app you provided doesn't contain react-native-gesture-handler or react-native-reanimated, are you sure it's crashing on your end?

the crash appeared after made changes to the babel.config.js

The only change you made to that file was:

      [
        "module-resolver",
        {
          root: ["./"],
          alias: {
            "@": "./",
          },
        },
      ],

I don't think it's possible for that change to cause the crashing behaviour you're describing.

I've created a new app from scratch, but even with your exact setup (-t bare-minimum), everything is still working fine. Here's the App.js I used for testing:

import { StyleSheet, Text, View } from "react-native";
import { GestureHandlerRootView } from "react-native-gesture-handler";
import ReanimatedSwipeable from "react-native-gesture-handler/ReanimatedSwipeable";

export default function App() {
  return (
    <GestureHandlerRootView>
      <View style={styles.container}>
        <ReanimatedSwipeable>
          <Text style={styles.swipeable}>Hi! Swipe me and it'll crash!</Text>
        </ReanimatedSwipeable>
      </View>
    </GestureHandlerRootView>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#fff",
    alignItems: "center",
    justifyContent: "center",
  },
  swipeable: {
    color: "black",
    backgroundColor: "tomato",
  },
});

I'll really need to get a working (crashing) reproducer app to help you with this issue.

@Mattis44

just saw that gesture-handler isn't available for RN 0.81
Just saw this cherry pick (#3688) merged to @next, is it possible to install the @next version from npm

That PR has already been released under version 2.28.0,
and react-native-gesture-handler is compatible with react-native 0.81 since version 2.28.0.

I tested this by creating an app with both react-native-gesture-handler 2.28.0 and react-native 0.81, and I can confirm that it works well.

[Mattis44]

oops, shared a repo with only the init commit ^^.
You'll get it tomorrow ! Sorry 🥲
