I get the following error when trying to build the iOS app.

The iOS project should successfully build and run.

Reproducible sample code

Podfile

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'MyApp' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for MyApp
  pod 'FBSDKCoreKit', '4.40'
  pod 'FBSDKLoginKit', '4.40'
  pod 'FBSDKShareKit', '4.40'
  pod 'GoogleSignIn', '~> 4.4.0'

  # Required for new version of react-native-device-info, see https://github.com/react-native-community/react-native-device-info#manual
  pod 'React', :path => '../node_modules/react-native'

  # Explicitly include Yoga if you are using RN >= 0.42.0
  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

  pod 'RNDeviceInfo', :path => '../node_modules/react-native-device-info'

  target 'MyAppTests' do
    inherit! :search_paths
    # Pods for testing
  end

end

target 'MyApp-tvOS' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for MyApp-tvOS

  target 'MyApp-tvOSTests' do
    inherit! :search_paths
    # Pods for testing
  end

end

# React-Native is not great about React double-including from the Podfile
post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end
    # It removes React & Yoga from the Pods project, as it is already included in the main project.
    targets_to_ignore = %w(React yoga)
    if targets_to_ignore.include? target.name
      target.remove_from_project
    end
  end
end

hey @alexstoyanov I had this same error. My mistake was using both pod install and react-native link <pakcageName> so I ran react-native unlink packageName. Then I went into the ios directory of my react native project and ran pod deintegrate && pod install then cd back to the root of the project and run react-native run-ios. everything is working great.

Correct.

And in regards to your above comment, I agree and learned it the hard way. I blame it on my lack of knowledge.

I’ll try reverting to the point before I “re-linked” RNDeviceInfo.
