Hi Apple. I created SourceCleaner that analyzes Swift Projects and identifies symbols (variables, functions, classes) and files that are no longer used in the project and offers to delete or comment those out. Please integrate that functionality directly into #Xcode. I think this should not be a standalone app developed by a single person somewhere in Buxtehude.
