NativeModules.SettingsManager.settings doesn't have AppleLocale field on iOS 13

[grindos]

React Native version:
0.59.9

iOS version on simulator:
13.0

Steps To Reproduce

1. Check the OS type.
2. If the OS type is not Android, try to get the locale.
3. Get the NativeModules.SettingsManager.settings object and take AppleLocale field from it.
4. Take only last two letters from the string to get the region name. E.g. for en-US will be returned US.

Describe what you expected to happen:
For iOS 12.2 and earlier the NativeModules.SettingsManager.settings object contained AppleLocale field, so everything worked correctly on the same React Native version. I expected that for iOS 13 it will work correctly too.

Code example:

  const locale = Platform.OS === 'android' ?
    NativeModules.I18nManager.localeIdentifier :
    NativeModules.SettingsManager.settings.AppleLocale;
  const localeLastChars = locale.slice(-2);

This is also happening to me on react-native version 0.61.3

It's the same for me but I'm using expo

I solved my problem with this https://docs.expo.io/versions/v34.0.0/sdk/localization/
And I used only Localization.locale

try this

const getDeviceLocale = () => {
  if (Platform.OS === 'ios') {
    let locale = NativeModules.SettingsManager.settings.AppleLocale // "fr_FR"
    if (locale === undefined) {
        // iOS 13 workaround, take first of AppleLanguages array  ["en", "en-NZ"]
        locale = NativeModules.SettingsManager.settings.AppleLanguages[0];
        if (locale) {
          return locale;
        }
    }
  }

  if (Platform.OS === 'android') {
    return NativeModules.I18nManager.localeIdentifier;
  }

  return 'pt-BR';
};

@sibelius
That code will come back with an error evaluating the t.proptypes

[grindos]

@secretgh @sibelius in fact, I'm using the same workaround at this moment and it works fine, but it would be great to have not a workaround solution, but make available AppleLocale at every moment. I don't think that iOS works without locale sometimes, especially if AppleLanguages is available
