Some Fundamental Methods

And, you know what, you might be able to solve that with some simple ways. We can better understand these solutions by using the cases below.

Method 1: 

1. Open your Podfile in your React Native project first.
2. Copy and paste this code at the bottom of your iOS/Podfile.

post_install do |installer|

  ## Fix for XCode 12.5

      find_and_replace("../node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm",

      "_initializeModules:(NSArray<id<RCTBridgeModule>> *)modules", "_initializeModules:(NSArray<Class> *)modules")

      find_and_replace("../node_modules/react-native/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm",

      "RCTBridgeModuleNameForClass(module))", "RCTBridgeModuleNameForClass(Class(module)))")

  end

def find_and_replace(dir, findstr, replacestr)

  Dir[dir].each do |name|

      text = File.read(name)

      replace = text.gsub(findstr,replacestr)

      if text != replace

          puts "Fix: " + name

          File.open(name, "w") { |file| file.puts replace }

          STDOUT.flush

      end

  end

  Dir[dir + '*/'].each(&method(:find_and_replace))

end

3. Conserve the Podfile.

4. Finally, use the terminal to run pod install.

5. Re-run/build your project!

Method 2:

Add this code in your Podfile.

post_install do |installer|

    ## Fix for XCode 12.5

    find_and_replace("../node_modules/react native/React/CxxBridge/RCTCxxBridge.mm", "_initializeModules:(NSArray<id<RCTBridgeModule>> *)modules", "_initializeModules:(NSArray<Class> *)modules")

    find_and_replace("../node_modules/react-native/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm", "RCTBridgeModuleNameForClass(strongModule))", "RCTBridgeModuleNameForClass(Class(strongModule)))")

  end

def find_and_replace(dir, findstr, replacestr)

  Dir[dir].each do |name|

      text = File.read(name)

      replace = text.gsub(findstr,replacestr)

      if text != replace

          puts "Fix: " + name

          File.open(name, "w") { |file| file.puts replace }

          STDOUT.flush

      end

  end

  Dir[dir + '*/'].each(&method(:find_and_replace))

end

Following that, you will notice an error related to Flipper:

Flipper-Folly/folly/synchronization/DistributedMutex-inl.h:1051:5: 'atomic_notify_one<unsigned long>' is unavailable

# Enables Flipper.

#

# Note that if you have use_frameworks! enabled, Flipper will not work and

# you should disable the next line.

# use_flipper!()

And removed the line # flipper post install(installer) within post install do |installer|.

Finally, reinstall your pods, recompile, and run your project.

Method 3:

1. yarn add -D patch-package

2. Go to node_modules/react-native/React/CxxBridge/RCTCxxBridge.mm

Change _initializeModules:(NSArray<id<RCTBridgeModule>> *)modules to _initializeModules:(NSArray<Class> *)modules

3. Go to node_modules/react-native/ReactCommon/turbomodule/core/platform/ios/RCTTurboModuleManager.mm

Change RCTBridgeModuleNameForClass(module)) to RCTBridgeModuleNameForClass(Class(module)))

4. yarn patch-package react-native
