title: xcode cloud adding workflow errors "this operation could not be complete"
body: <p>Developing an iOS app on react native, trying to use xcode cloud for the first time.</p>
  <p>When adding a workflow I'm getting this error:</p>
  <p><a href="https://i.stack.imgur.com/bjHq7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bjHq7.png" alt="enter image description here" /></a></p>
  <p>As you can see the error message isn't useful, and I couldn't find anything on line (probably because it's a new beta feature by xcode)</p>
  <p>Any ideas on how to even approach this?</p>
  <p>In case it matters, I tried various variations of this file as the documentation:</p>
  <pre><code># ios/ci_scripts/ci_post_clone.sh (it's executable)
  
  #!/bin/sh
  
  ## V1
  brew install cocoapods
  brew install node
  brew install yarn
  yarn
  pod install
  
  ## V2
  export HOMEBREW_NO_INSTALL_CLEANUP=TRUE
  brew install cocoapods
  # have to add node yourself
  brew install node@16
  # link it to the path
  brew link node@16
  
  brew install yarn
  
  # Install dependencies you manage with CocoaPods.
  yarn
  pod install
  # the sed command from RN cant find the file... so we have to run it ourselves
  sed -i -e $'s/ &amp;&amp; (__IPHONE_OS_VERSION_MIN_REQUIRED &lt; __IPHONE_10_0)//' /Volumes/workspace/repository/ios/Pods/RCT-Folly/folly/portability/Time.h
