Same thing here

Works nice with simulator but not with device

Can you send us more info about the error?
What branch?
We're working fine with develop.

@diegolmello my branch is single-server

Just try to run debug configuration on device

Looks like it tries to build main.jsbundle seeing that we run it on devce while it has to use metro server

[alanXdev0]

the same as @stephenkopylov, on single-server branch running on debug, while release works correctly

[stephenkopylov]

I found a little bit "hacky" solution

Run release configuration with development provision profiles - you'll have "bundled" version of app but it will run

It's the same also with XCode 12.4 ... as soon as I want to run it in XCode on a physical device in debug mode I'm getting this error.

It's related to Hermes, apparently facebook/hermes#46
There's a new version of React Native pointing to newer Hermes, so it might have been fixed there (we'll update soon).
We all see that it's a debug issue only, so it should be fine on release.
As workaround, we could either work on simulator only or disable Hermes.
To disable Hermes, you need to:

• set here to false https://github.com/RocketChat/Rocket.Chat.ReactNative/blob/develop/ios/Podfile#L11
• run npx pod-install

I was able to fix this issue by using node v15.12.0

Thanks you!. Someone fix this issue ?

Seems inconsistent, maybe it's lack of ios dev experience, but sometimes Xcode builds it no problem others it fusses. When it does complain I just disable Hermes and it works.
