prompt: Your task is to convert the following English description into an ASCII tree format.
  
  swift is a head directory that incorporates 3 subdirectories: non-swift-package-project, swift-package-project and swift-package-project-with-config.
  At the main level, 'non-swift-package-project' has 1 nested folders: src.
  Within directory hierarchy 'non-swift-package-project / src', Within 'src', you'll find 1 subdirectory elements for code structure.
  In nested path 'non-swift-package-project / src / folder', Inside 'folder', you'll find it sits empty.
  Back to the top level.
  At the top level, 'swift-package-project' organizes 1 directory entries: src.
  Within directory hierarchy 'swift-package-project > src', Within 'src', you'll find 1 subdirectories for code structure.
  In nested path 'swift-package-project > src > folder', 'folder' is barren.
  At the main level, 'swift-package-project-with-config' houses 1 directories: src.
  At level 2, in directory path 'swift-package-project-with-config / src', The 'src' collection includes 1 folders for code organization.
  At level 3, in directory path 'swift-package-project-with-config > src > folder', Inside 'folder', you'll find it is blank.
  Back to the top level.
