Tic Tac Toe in objective C on mac Xcode

CodeNewbie (2)
Ok so i am extremely new to coding anything, I am taking an online course and I am trying to build Tic Tac Toe for an assigment. I don't want people to write my code and i dont want to just cut/paste someone else's code without understanding what I am doing, so i've been searching TTT games and using them as examples of what I've written below. it is far from finished, I am using the output window to play the game, not building it for an iphone or anything else.

I just have a few basic questions:

1) how do I get the [#]'s in the TTT board to change to X or O
2) how do I get the computer to alternate between player 1 and player 2

I managed to do the things you mentioned, in C++ though, but they're almost the same I think. Maybe you could take a look into my code, it may not be so effective or short, because I'm a beginner at this. But it works, most of the time.

I found a lot of C++ code that looks pretty similar, i just do not know how to translate bits of it into what i am doing with xcode on a mac. the >>array>> that you use doesnt work on xcode/mac.
