Hey @markamccorkle thanks for filing. Unfortunately this isn't actionable without a repro case - if you can post a repo we can reopen and take a look

[OrangeFlavoredColdCoffee]

hi，I have the same problem，can you tell me how you fix this？

[hpelitebook745G2]

@rickhanlonii This happened to me as well when setting up fresh project with cocoa pods. Here's my podfile:

platform :ios, '9.0'

project 'boilerplate', 'Staging' => :debug

target 'boilerplate' do
  rn_path = '../node_modules/react-native'

  use_frameworks!

  pod 'yoga', path: "#{rn_path}/ReactCommon/yoga"
  pod 'DoubleConversion', :podspec => "#{rn_path}/third-party-podspecs/DoubleConversion.podspec"
  pod 'Folly', :podspec => "#{rn_path}/third-party-podspecs/Folly.podspec"
  pod 'glog', :podspec => "#{rn_path}/third-party-podspecs/glog.podspec"
  pod 'React', path: rn_path, subspecs: [
    'Core',
    'CxxBridge',
    'DevSupport',
    'RCTActionSheet',
    'RCTAnimation',
    'RCTGeolocation',
    'RCTImage',
    'RCTLinkingIOS',
    'RCTNetwork',
    'RCTSettings',
    'RCTText',
    'RCTVibration',
    'RCTWebSocket',
  ]

  pod 'RNVectorIcons', :path => '../node_modules/react-native-vector-icons'
  pod 'RNGestureHandler', :path => '../node_modules/react-native-gesture-handler'

end

While here's my Build Phase (Linked automatically):

Version:
React Native: 0.59.8

I also tried to create another fresh project but without cocoapods and it worked without problems. Is there any setup done for cocoapods to work?

@hpelitebook745G2 have you fix it?
