How to fix React Native App not building for iOS

Question

I'm having trouble building my react native app for iOS. For android it builds perfectly fine. For iOS, the project will build but not archive. Here is the error code when attempting to archive my project:

1) Target 'React-Core.common-AccessibilityResources' has create directory command with output '/Users/jacobcarpenter/Library/Developer/Xcode/DerivedData/LFGOPocker-gaqwcsmtamkdjtbdiwhnzcvmexjk/Build/Intermediates.noindex/ArchiveIntermediates/LFGOPocker/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/AccessibilityResources.bundle'
2) Target 'React-Core.common-CoreModulesHeaders-AccessibilityResources' has create directory command with output '/Users/jacobcarpenter/Library/Developer/Xcode/DerivedData/LFGOPocker-gaqwcsmtamkdjtbdiwhnzcvmexjk/Build/Intermediates.noindex/ArchiveIntermediates/LFGOPocker/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/AccessibilityResources.bundle'

Few things to state: Running React-native 0.63, Podfile and deployment targets are all on 11

Edit: when running from the command line I receive this error

      '/Users/jacobcarpenter/Library/Developer/Xcode/DerivedData/LFGOPocker-bzowsupbiktzuzaaadvokqxbgvzq/Build/Intermediates.noindex/ArchiveIntermediates/LFGOPocker/BuildProductsPath/Release-iphoneos/YogaKit/YogaKit.modulemap'
      not found```

Answer 1

I fixed this error by deleting 'React-Core.common-AccessibilityResources' from my pod targets. When attempting to archive, make sure you are not using .xcodeproj and using your workspace. Even if you think you are using workspace triple check. Also if you try archiving through the command line you must specifically state workspace.

For anyone who is not very experienced with Pods, add the following lines to your Podfile (RN 0.63.2):

target 'yourapp' do

  # your pods go here

  config = use_native_modules!

  use_react_native!(:path => config["reactNativePath"])


  # Enables Flipper.
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable these next few lines.

  use_flipper!
  post_install do |installer|
    flipper_post_install(installer)

    ################### ADD THE FOLLOWING #########################
    installer.pods_project.targets.each do |target|
      if target.name == "React-Core.common-AccessibilityResources"
        target.remove_from_project
      end
    end
    ###############################################################

  end
end
