If you don't want to use VCS for creating patch then you can use diff tool. You can create patch for one file using

diff -u original.c new.c > original.patch

Or

diff -rupN original/ new/ > original.patch

For entire folder

First check in the Xcode Downloads whether the Command Line Tools are downloaded or not. if not first download that and then follow the below procedure

In Terminal go to the directory where we need that Patch File and execute the Command svn diff > somename.patch then you will get a patch file in that directory
