I am currently developing an app in Xcode 4 for the IPhone and I have com across this error, "Thread 1: Program Received Signal: SIGABRT", This error is in my main.m code.

//
//  main.m
//  MyCard
//
//  Created by Nazar Gren on 2/2/12.

#import <UIKit/UIKit.h>

#import "mycardAppDelegate.h"

int main(int argc, char *argv[])
{
     @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([mycardAppDelegate         class]));
     }
 }

My error appears on the line under the @autorelease pool line. In the debugger, I get this message, "This generally means that another instance of this process was already running or is hung in the debugger." And this error only occurs when I attempt to debug my app. My app doesn't even run. Can anyone help? It would be greatly appreciated.

If this is happening on the simulator, restart your computer. If this is happening on a real device, restart the device, and if the problem persists, restart the computer as well. This problem has occurred for me multiple times, because of a zombified process left on the device/simulator when a test is unexpectedly aborted. A simple reboot will fix it.
