Actual results

I am running into an issue with FBSDKCoreKit where on some environments I get the error Library not loaded: @rpath/FBSDKCoreKit.framework/FBSDKCoreKit unless I add it to Frameworks, Libraries, and Embedded Content

But while that resolves the issue on problematic environments, it creates an issue on all other environments

Error (Xcode): Multiple commands produce '/Users/admin/Library/Developer/Xcode/DerivedData/Runner-adwcstkmsmzcjgdzgisfheqwwytp/Build/Intermediates.noindex/ArchiveIntermediates/Runner/InstallationBuildProductsLocation/Applications/Runner.app/Frameworks/Foo.framework'

So now we have this 'seesaw' problem where fixing the issue on one environment causes all other environments to break.

I have created a Stack Overflow question, as well as an issue for the downstream consumer of Facebook SDKs

Was able to resolve it by running arch -x86_64 pod update on my 14" M1 Pro

Complete command:

function pod-nuke(){
  pod cache clean --all
  rm -rf "$HOME/Library/Caches/CocoaPods"
  rm -rf "$HOME/Library/Developer/Xcode/DerivedData/*"
  rm -rf Pods
  arch -x86_64 pod update
}

Apparently this line was added to my .zshrc at some point, I think it was recommended by brew or something? In any case, I was getting errors when trying to run arch -x86_64 pod update until I removed this:

# ruby
if [ -d "/opt/homebrew/opt/ruby/bin" ]; then
  export PATH=/opt/homebrew/opt/ruby/bin:$PATH
  export PATH=`gem environment gemdir`/bin:$PATH
fi
