[React Native] Support Hermes on iOS (react-native 0.64)

[mrousavy]

react-native 0.64-rc0 released, which includes Hermes support for iOS. (see react-native-community/releases#214) Currently, all appcenter codepush commands fail, because the bundle-generation is hardcoded in such a way that it isn't expecting a hermes js executor/bitcode instead of JSC for iOS builds, so at the moment codepush does not work.

Is hermes support planned for codepush?

Is there any update in this matter?

[mrousavy]

I managed to actually build the JS bundle using the appcenter CLI, and it actually works with Hermes. The problem is, that the bundle is not built with the Hermes compiler (hermesc), meaning it is not in bytecode format and the app will therefore not run with maximum performance.

Hi! Thanks for getting in touch with us!
Hermes for IOS is on our roadmap but we don't have ETA for this. We will do it as soon as possible and notify you when we will have any updates.

@AnastasiaKubova are there any updates on this?

[AnastasiaKubova]

We don't have ETA for this. We will notify here when we will have any updates.

We need this also. It would be nice if your documentation clearly listed the limitations for various versions of react-native.

I'm closing this issue since #1461 was merged.
