Apple Mac Developer Library
The Library directories are where the system and your code store all of their related data and resources. In macOS, this directory can contain many different subdirectories, most of which are created automatically by the system. In iOS, the app installer creates only a few subdirectories in ~/Library (such as Caches and Preferences) and your app is responsible for creating all others.
Table A-1 lists some of the common subdirectories you might find in a Library directory in macOS along with the types of files that belong there. You should always use these directories for their intended purposes. For information about the directories your app should be using the most, see The Library Directory Stores App-Specific Files.
