Undefined symbols for architecture arm64

[yimingtang]

Hello, again. I'm following emission in my project. When I tried to archive a release build, an Undefined symbols for architecture arm64 error occurs. Something like this:

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_RCTRootView", referenced from:
      objc-class-ref in libPegasus.a(PEGComponentViewController.o)
  "_OBJC_CLASS_$_RCTBundleURLProvider", referenced from:
      objc-class-ref in libPegasus.a(Pegasus.o)
  "_OBJC_CLASS_$_RCTBridge", referenced from:
      objc-class-ref in libPegasus.a(Pegasus.o)
  "_OBJC_CLASS_$_RCTConvert", referenced from:

After a little investigation, I found this issue. However, most of the solutions are for pure "react native" apps which were created by RN CLI.

I'm afraid that you may come across this issue, too. Any ideas?

😢 My fault. I wrote the following line in my Podfile.

pod 'React/RCTWebSocket', :configuration => 'Debug'

It breaks the release build. Don't know why though. Removing this line fix the issue. So I'll close the issue. I know eigen turns off React Native's debug mode. It won't happen in your project. I apologize for bothering you.
