I18nManager.forceRTL doesn't applies changes in first app load

i18nmanager forcertl is not working
i18nmanager expo
expo rtl
i18nmanager import
i18nmanager npm

I have an app that created by awesome React-native and my layout designed to be in RTL mode. I've set up an option for forcing the layout to be RTL but my option doesn't works in first app load after installing. This feature applies in second run.

I wrote this option in our index.js:

import React, { Component } from 'react';
import { I18nManager } from 'react-native';
import { Provider } from 'react-redux';


class App extends Component {
  render() {
    return (
      <Provider store={store}>
        <PersistGate loading={null} persistor={persistor}>
          <MainStack />

export default App;

I had the same problem and solved it by invoking forceRTL in MainApplication.java in the onCreate method.

import com.facebook.react.modules.i18nmanager.I18nUtil;

  public void onCreate() {
    SoLoader.init(this, /* native exopackage */ false);

    I18nUtil sharedI18nUtilInstance = I18nUtil.getInstance();
    sharedI18nUtilInstance.allowRTL(this, true);

On IOS add in the AppDelegate.m

NSURL *jsCodeLocation; // this probably already exists!
[[RCTI18nUtil sharedInstance] allowRTL:YES];
[[RCTI18nUtil sharedInstance] forceRTL:YES];

After a week finally i found a logicly way to solve this issue with using Redux & react-native-restart plugin. I'm also use a nice splash screen to user don't show a restarting progress for this purpose.

So let's dive into code:

Redux action:


export const getAppLayoutDirection = () => ({

export const setAppLayoutDirection = direction => ({

Redux Reducer:

import {
} from '../actions/app';

const initialState = {
    layout: 'ltr',

const reducer = (state = initialState, action) => {
    switch (action.type) {
        return {
        return {
          layout: action.direction,
        return state;

export default reducer;

Home Screen:

import PropTypes from 'prop-types';
import { connect } from 'react-redux';
import RNRestart from 'react-native-restart'; // Import package from node modules
import { getAppLayoutDirection, setAppLayoutDirection } from '../actions/app';

class Home extends PureComponent {
   constructor(props) {

     if(this.props.layout === 'ltr'){

  componentDidMount() {
     if(this.props.layout && this.props.layout === 'rtl'){

const mapStateToProps = (state) => {
  const { layout } = state.app;
  return {

export default connect(mapStateToProps)(Home);

I18nManager.forceRTL doesn't apply changes on react , forceRTL doesn't apply changes on react-native components without i force RTL using I18nManager but the app needs to be reloaded to� call I18nManager.forceRTL method on the onValueChange param of the Switch component; call setLanguage method to set RTL language (arabic, hebrew …) Expected Behavior. Render the screen with the chosen RTL language and alignement. Actual Behavior. Render the screen with chosen language but screen components doesn’t change alignement from right to left.

I went through the same issue this helped me. This is abit modified answer without the need to use redux.

First you check current state with I18nManager.isRTL then forceRTL if not and restart with react-native-restart.

   constructor(props) {          
      //Force RTL
      if(I18nManager.isRTL != true){

I18nManager.forceRTL doesn't applies changes in first - html, First you check current state with I18nManager.isRTL then forceRTL if not and restart with react-native-restart. constructor(props) { //Force RTL if(I18nManager. I18nManager.forceRTL(true) But unfortunately, it doesn’t work properly with many libraries. So, if you’re building a library, always test that it works properly with react-native link. It

Make sure that on iOS, next to having added all relevant RTL locales to your Xcode project (e.g. Arabic). You should also make sure that your .ipa contains .lproj folders for each locale. Otherwise iOS doesn't pick up on the supported languages.

This is a common issue in React Native projects where you don't typically write a lot of Swift/Obj-C code & most of the translations happen in JavaScript (apart maybe from some stuff in you Info.plist).

  • Seems to be a know bug: github.com/facebook/react-native/issues/11475 Does putting the rtl tag into your html doc not work?
  • I want to force RTL in ios I add [[RCTI18nUtil sharedInstance] allowRTL:YES]; in AppDelegate.m but it does not work, any tips?
