git checkout for xcode -


so i've been watching videos facebook mobile devcon 2013 (http://www.youtube.com/watch?v=mluautbgvem) on youtube , every time explains new or new checkout , new code added project. different versions of project? how work?

can explain git checkout , needed set 1 up?

edit speaker git checkout on 38:49

the speaker has git repository multiple branches or tags each stage of demo/walk-through. git checkout used checkout given branch/tag/hash , files updated in-place. xcode detect files changes , refresh editor view , groups , files pane.

to create kind of thing yourself, develop code , create branches @ various points using command git branch step2, git branch step3 etc. after latest commit made.

when doing demo, can git checkout step3 move point in commit tree.
