I use user.home to do things like:
String userHomePath = System.getProperty("user.home"**);
myFileDialog.setDirectory(**userHomePath + "/Documents");
In my app, the user selects where he wants to export individual files, such
as CSVs and PDFs. These are files he'll use outside of my app.
If user.home points to the app's sandbox Container, it will break this
usage. Opening a file dialog to
/Users/Bob/Library/Containers/my.app/Data/Documents will definitely confuse
the user and if they save a file there, they will never be able to find it
later from outside of my app.
Yes, I understand the whole sandboxing concept. I'm not asking for
unrestricted access to the file system. I use the "com.apple.
security.files.user-selected.read-write" entitlement so that the user can
select where he wants to save files, and I want to present him with a
standard, well-known, default location for that (like ~/Documents).
If user.home doesn't point to the user's actual home folder (i.e.
NSHomeDirectoryForUser), it makes creating a standard, well-known location
path (like ~/Documents) much more difficult. (And IMHO, it breaks the
definition of the user.home property: "User home directory", not "App home
directory".)
