I had a similar issue. Running dev version on iOS simulator works fine, but when I try to archive app in XCode, I got Use of undeclared identifier error.

Solution

In AppDelegate.m file, find header files you included:

AppDelegate.m

#import <React/RCTBridge.h>
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>

#ifdef FB_SONARKIT_ENABLED
#import <FlipperKit/FlipperClient.h>
#import <FlipperKitLayoutPlugin/FlipperKitLayoutPlugin.h>
#import <FlipperKitUserDefaultsPlugin/FKUserDefaultsPlugin.h>
#import <FlipperKitNetworkPlugin/FlipperKitNetworkPlugin.h>
#import <SKIOSNetworkPlugin/SKIOSNetworkAdapter.h>
#import <FlipperKitReactPlugin/FlipperKitReactPlugin.h>

#import <Some/Dependency.h> <--- ❌ this might be the problem

If you've imported your dependency under this line:

#ifdef FB_SONARKIT_ENABLED

please move them up to before it.

For example:

#import <React/RCTBridge.h>
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
#import <Some/Dependency.h> <--- ✅ Right here

#ifdef FB_SONARKIT_ENABLED
#import <FlipperKit/FlipperClient.h>
#import <FlipperKitLayoutPlugin/FlipperKitLayoutPlugin.h>
#import <FlipperKitUserDefaultsPlugin/FKUserDefaultsPlugin.h>
#import <FlipperKitNetworkPlugin/FlipperKitNetworkPlugin.h>
#import <SKIOSNetworkPlugin/SKIOSNetworkAdapter.h>
#import <FlipperKitReactPlugin/FlipperKitReactPlugin.h>

Reason

FB Sonar Kit or Flipper is a debugging tool. It might get disabled when archiving.
