Library 'RCTDeprecation' not found error after upgrading to 0.78.2

[MufeedaFi]

Description

I upgraded my RN app from version 0.66.4 to 0.78.2. In iOS, the pod installation is completed but on running the app i'am getting the error Library 'RCTDeprecation' not found. Any idea?

This is my ios pod file:

require Pod::Executable.execute_command('node', ['-p',
  'require.resolve(
    "react-native/scripts/react_native_pods.rb",
    {paths: [process.argv[1]]},
  )', __dir__]).strip

platform :ios, '15.1'
prepare_react_native_project!

ENV['RCT_NEW_ARCH_ENABLED'] = '0'

linkage = ENV['USE_FRAMEWORKS']
if linkage
  Pod::UI.puts "Configuring Pod with #{linkage}ally linked Frameworks".green
  use_frameworks! :linkage => linkage.to_sym
end

$react_native_path = nil

target 'App' do
  config = use_native_modules!

  $react_native_path = config[:reactNativePath]

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

  permissions_path = '../node_modules/react-native-permissions/ios'
  pod 'Permission-Camera', :path => "#{permissions_path}/Camera"
  pod 'Permission-Microphone', :path => "#{permissions_path}/Microphone"

  pod 'customerio-reactnative/apn', :path => '../node_modules/customerio-reactnative'
end

target 'Notif' do
  platform :ios, '15.1'
  pod 'customerio-reactnative-richpush/apn', :path => '../node_modules/customerio-reactnative'
end

post_install do |installer|
  react_native_post_install(
    installer,
    $react_native_path,
    :mac_catalyst_enabled => false
  )

  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '5.6'
    end
  end
end

What might be causing the issue? I added pod 'RCTDeprecation', :path => '../node_modules/react-native/ReactApple/Libraries/RCTFoundation/RCTDeprecation' but the issue is not fixed. Plz help!!

1. upgraded my RN app from version 0.66.4 to 0.78.2.

3. Run /Build the iOS app

1. double check that your Podfile align with the one we provide: https://github.com/react-native-community/template/blob/0.78-stable/template/ios/Podfile
2. clean up your project: cd ios && rm -rf Pods/ Podfile.lock *.xcworkspace && cd .. && rm -rf yarn.lock node_modules
3. Reinstall dependencies: yarn install && cd ios && bundle install && bundle exec pod install
4. Try to build: open YourApp.xcworkspace, and then ⌘ + B

You don't have to add anything to your pods, as RCTDeprecation is part of React Native and should be installed for you.
I think you have some cache issues

Thanks!

But with this podfile, iam getting error : node_modules/@react-native-community/progress-view/common/cpp/react/renderer/components/progressview/RNCProgressViewState.h:3:10 'react/renderer/components/progressview/Props.h' file not found as mentioned in this
react-native-progress-view/progress-view#154.

So would need to add ENV['RCT_NEW_ARCH_ENABLED'] = '0' to the podfile to fix that, which again generates error Library 'RCTDeprecation' not found

[cipolleschi]

You should NOT set RCT_NEW_ARCH_ENABLED to 0 in your app.
this disables the New Architecture and it is never a workaround for a bug that you are seeing.

If you are getting that error, the alternatives are that:

1. you need to bump @react-native-community/progress-view to a new version that supports the New Architecture properly (it looks like the library is wrongly setup)
2. you need to clean the ios/.build folder and re-run pod install to make sure that codegen runs with the new pods.
