I developed several apps with React Native, and the build process in Xcode allowed to work them without metro bundler running across, relying on included jsbundle file.
But then I joined new project, which relies on metro bundler along Xcode build in order to make app work and exposes developer tools, even if __DEV__ is false in JS. So, when we uploaded archived build to TestFlight app crashes after splash screen and sentry gives us no clue at all.
I'm not an iOS nor objective-c developer, so I don't even know where to start from.
React Native version is 0.53
