Why are you adding this?

Because on iOS side without this variable release builds is not rendered by hermes.

Nope you should not be needing to add export USE_HERMES=true to your .xcode.env file. I think there is something going on in your setup.

I think there is fuzzy situation, when I add hermes_enable value to Podfile I expected to release build would have been byte coded version as same as android without installing pods with USE_HERMES=1 which is not seems on documantation also.
I'm not quite sure but there is fuzy situation which is not explained on this type. We need to add this USE_HERMES=1 bundle exec pod install or mine idk

Hermes is the default engine. If you don't specify anything, that would be used by default.
I think that your setup has some issue and that's not the base situation for all our users, so we should not add this into the documentation

Just to clarify, this flag is only used during the pod installation process. For example, if I change it from true to false, the change won’t take effect until I run pod install again isn't? and this situation is not explicitly informed, I think this case should been added docs, I could add related information in docs if you aggree with me. |

@zaferatli correct. That is an env var for Cocoapods only, which controls whether Hermes should be installed. |
on iOS side with this value hermes isn't working.
