As you can see the method returns the correct value
.../Library/
and the file name is appended, so the final result is a valid file path,
like
.../Library/filename.ext
Indeed you can see that the root path undergoes a string manipulation, so
there are no extra '/'.
Even if the root is like '.../Documents/', the string manipulation strips
the entire final part before adding the replacement.
So what's the problem? Maybe default FileSystem permissions in the XCode
project are not working in OS14? Something else?
