Mac OS - XCode: How to show line numbers in editor.

Well I'am back(not that anybody was missing me) with another short simple tip to use on your day to day coding, this time for Xcode on mac os; to be more specific XCode 6.1(Although it is mostly similar from version 4.x,5.x till 6.1).
XCode as many of you may already now, but for the ones that don't, is Apple's IDE for developing apps either safari, MacOS, iOS or ipod, and other kind of apps.
Today's well see viewing simple line numbers on the editor, this is not very difficult to achieve but if you were kind of confused like I was at the begining a little help comes in handy.
To show line numbers:
1-just open XCode(the option is accesible with or without opening a project), 2- and then go to the tool bar and click on the 'XCode' option that will be the first one from left to right, 3-Now to to 'Text editing' from the floating menu options tab, 4-and finally just check the 'Line numbers' box, et voila! this is ready.

Hope you liked it, and see you soon with something else I'll find usefull to share.
