iOS: Accessibility Language Support

[amarlette]

Requires API Proposal

This issue may require a new API, or a change to an existing API. An API proposal should be added and discussed before proceeding with implementation. The API proposal can be added in the comments of this issue or linked as a separate issue.

Description

It should be possible to set a specific language for text to be read by VoiceOver. Text to be read is not always the same as the system-wide locale.

React Native version:

v0.63

Expected Behavior

There could be an attribute like "accessibilityLanguage = {...}" which would be set on an applicable type of text.

iOS Details

It seems feasible that the native accessibilityLanguage property could be bridged for applicable components.

I'd like to tackle on this issue as the first contribution to this repo!

I ran into this today and was surprised there wasn't a way to do this yet. Setting language per element can at times be essential; think flashcard and language learning apps for example. Nothing more charming then hearing an american TTS voice mangle a french sentence, I can assure you.

I'm also running into this problem. I want to fix it.

@inatonix Are there any updates?

Thank you, now I'm working on another issue and I'm not working on this one.

Hello! I found myself implementing this for personal reasons, and I think I already have a working branch with a possible implementation. I added an accessibilityLanguage prop typed as string to all the most common elements in RN (so, not just to the Text component). This prop is just a bridge to the iOS native property linked in the issue. I am obviously open to changes! Let me know if and when It's ok for you to open a PR 🙂
