I am using react-native-twitter sign in, and followed all the steps in the official documentation, but getting
Use of undeclared identifier 'Twitter' in AppDelegate.m file
this error while Archiving the IOS app, but it works fine while running on simulator, what should be the problem ?
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.
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>
FB Sonar Kit or Flipper is a debugging tool. It might get disabled when archiving.
