Description

This is a feature request. <Switch /> components do not support the accessibilityLabel prop.

Motivation: I am using the Appium testing framework as it is the preferred framework for integrating with BrowserStack. Appium highly recommends using accessibilityLabel to identify components, allowing developers to fallback on XPath as a last resort.

React Native version:

I am currently using react-native@0.62.1 but looking at the online docs for <Switch /> I see that the prop is still not supported in latest (0.63).

Steps To Reproduce

1. Render <Switch accessibilityLabel="test" />
2. <android.widget.Switch> has no content-desc property. This property should have the same value as the accessibilityLabel prop.

Expected Results

When viewed in Appium or another app view source explorer, the <android.widget.Switch> node in the rendered tree will have a content-desc="test" (see the ViewGroup for reference). The correct corresponding property will be set on iOS.

Snack, code example, screenshot, or link to a repository:

import React from 'react';
import { Switch, View } from 'react-native';

function App() {
  return <View><Switch accessibilityLabel="test" /></View>
}
