Expected Behavior

• What do you expect should be happening?
• Include a screenshot or video if it makes sense.

Hi @MaheshKaemSolutions . Do you find any solution for this??

[MaheshKaemSolutions]

@miklosherald09 actually this library doesn't support simulators, but you can build this library on real device and it's working fine over there.

For people encounters this problem, it can be resolved by the following steps:

• First, adding the following scripts to your Podfile

installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
  end
end

Then, it should look like

target 'NewRN' do
  config = use_native_modules!

  use_react_native!(
    :path => config[:reactNativePath],
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/.."
  )

  target 'NewRNTests' do
    inherit! :complete
    # Pods for testing
  end

  post_install do |installer|
    # https://github.com/facebook/react-native/blob/main/packages/react-native/scripts/react_native_pods.rb#L197-L202
    react_native_post_install(
      installer,
      config[:reactNativePath],
      :mac_catalyst_enabled => false,
      # :ccache_enabled => true
    )
    
    # Adding these lines below.
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
      end
    end
    
  end
  
end

Don't forget to execute npx pod-install in your root directory or pod install in ios directory.

• Second, adding arm64 to Any iOS Simulator SDK in Build Settings->Arthitectures->Excluded Architectures->Debug->Any iOS Simulator SDK

Then, it looks like the following screenshot

Finally, clean your xcode and run any simulator if you like. It should work as expected.
