so i am just trying to learn obj-c
i have this book:

Programming in Objective-C (Developer's Library)
Programming in Objective-C (Developer's Library)

so i just wanna make my first hello world app
but this (old) book still refers to project builder, the old xcode
my code for the app looks like this:

//
//  main.m
//  prog2
//

#import <stdio.h>

int main(int argc, char *argv[])
{
    printf ("Hello World!!!n");
	
	return 0;
}

thats in the main.m file
and i selected cocoa application as my choice at the beginning

i know my code is fine,
its just that xcode doesn't like this
i hit build and go and nothing happens
what do i do

thnks

Are you familiar with any GUI development at all?

That program would be run from a command line and would only work from a shell prompt on a jailbroken iPhone. It is basically a C program, not Objective-C.

Look for the jailbreak Hello World sample to get a vague idea - I believe the main.m has changed in 2.x:
