Looks good, let's try it out...

It seems there is still an issue:

[INFO] copy /Users/runner/work/Parse-SDK-iOS-OSX/Parse-SDK-iOS-OSX/docs to /Users/runner/actions_github_pages_1678225778587
  cp: no such file or directory: /Users/runner/work/Parse-SDK-iOS-OSX/Parse-SDK-iOS-OSX/docs/*
  cp: no such file or directory: /Users/runner/work/Parse-SDK-iOS-OSX/Parse-SDK-iOS-OSX/docs/.*

Could the path be incorrect, because it contains two times Parse-SDK-iOS-OSX?
