Here is my Podfile. There are some options that you might want to turn on or off:

platform :ios, '12.1'

target 'app_test' do
  config = use_native_modules!

  use_react_native!(
    :path => config[:reactNativePath],
    # to enable hermes on iOS, change `false` to `true` and then install pods
    :hermes_enabled => false
  )

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

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable the next line.
  use_flipper!()

  post_install do |installer|
    react_native_post_install(installer)
    __apply_Xcode_12_5_M1_post_install_workaround(installer)
    `sed -i -e  $'s/__IPHONE_10_0/__IPHONE_12_0/' Pods/RCT-Folly/folly/portability/Time.h`

    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
          # config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'arm64'
          config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.1'
          # config.build_settings['ENABLE_BITCODE'] = 'NO'
        end
      end
  end
end

@shahidjabbar thanks for the idea. I tried Rosetta mode and cleaning the derived data directory and that did not help. I wonder if the problem is related to user_target_xcconfig being used in https://github.com/pytorch/pytorch/blob/master/ios/LibTorch.podspec#L25

I read from another project (https://code.videolan.org/videolan/VLCKit/-/issues/498) that user_target_xcconfig has been deprecated and should be avoided.
