how do I contact Gabe, the objective C instructor, directly? Mark

// // main.m // mark's experiment // // Created by mark on 11/11/16. // Copyright © 2016 mark. All rights reserved. //

import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) { @autoreleasepool { // insert code here... NSLog(@"Hello, World!"); }

int size;
 size = 13; {
// insert code here...
NSLog(@"size is: %i", size);
 }

return 0;

}

When I run this on Xcode, the builder is successful. When I run it as my first project, it responds as a bummer.

When I attempt to remove, "hello, world!", on Xcode, the build is unsuccessful.

Is there an obvious reason for this?

Thanks, Mark

Hi there! Here's something important to note about challenges. They are testing for very specific things. It's important to try not to do anything the challenge doesn't explicitly ask for. Even if functional outside the challenge, it can still cause the challenge to fail . And you've gone way above and beyond what was required here. The entirety of the code that will pass both steps of this challenge is two lines.

Here's what it was looking for:

int size = 13;
float foodPrice = 3.50;

As for contacting Gabe directly, you could try tagging him here on the forums by using the @ sign and typing his name. A list should pop up with users connected to this forum that you can select from.

Hope this helps! :sparkles:
