The -@ option to ls will list extended attributes, including resource forks.
As to the nature of the file, lsof will show the file descriptor Xcode is using to access the file. You can write a simple DTrace command to get stack traces from calls which write to that file, which might provide some clue as to how Xcode is using it. For example, assuming the fd is 17:
sudo dtrace -n 'pid$target:libSystem*:write*:entry /arg0 == 17/ {ustack();}' -p <pid of Xcode>
Cheers,
Ken
