Coding Help

Hi everyone, I am ,, well not new to coding, I have played around with a few things in my life,, as a hobby, got a bit of addressing experience from the old electronics engineering course, back in the day. I picked up a mac book pro a while ago, and have gone through many tutorials for xcode. I have been playing with 3.2.6 i believe.
Well to I would like to say its an interesting system and not as bulky, as I was expecting when I started. I have been working on a small app to see if I can do it,,, and I am wondering where is the best place to ask questions regarding Xcode 3.26 and its components.
I am looking for some help to apply some things I have not fully got together. I am talking on a small scale. Would this be the place to ask questions you cant get on a tutorial or in a book, Or is there a better place for that?
Thanks in advance for all the help
