Bring up a project or create a new one in XCode. Under the "Project" menu choose "Class Browser". This will give you a list of Classes. Click on a class name to see its .h file. Click on the book symbol to the right of the class name to get its Reference doc.

This may not be a complete list, but it's a helluva good start.

Dejo ... are there additional classes? How can we see them pse?

There are classes from all frameworks (pretty much). Also, there are classes for any libraries you include in your project (for example, AdMob classes). Then there are all the classes out there created by developers that have made them public. So, in other words, the "list of all classes" is nearly unlimited.

So, I ask again, why do you need to see this list?
 
ALL classes for what? The Foundation Framework? The UIKit? Something else? And for what purpose do you need this list?

All the classes under NSObject here...

as the guy mentions in this tutorial

(under "homework".... he says to start with class "NSString" for example, but I simply would like to see a list of ALL classes at level where NSString is, i.e., all classes under NSObject...) thank you...
