Xcode 5.1.1 crashes

Question

Hi everyone! I have very big problem. When I try to run this code in Xcode
//  main.m
//  object-c
//  Created by Ivan on 06.06.14.
//  Copyright (c) 2014 Ivan. All rights reserved.
#import <Foundation/Foundation.h>
int main(int argc, const char * argv[])
    @autoreleasepool {
        // insert code here...
        NSLog(@"Hello, World!");
    return 0;
Xcode says "Build Succeeded" and then a few seconds later it says :
" Could not launch “objective c 2"
process launch failed: invalid host string: '(null)”
And then app suddenly crashes
i don't know to do
Please help!!!!
