I'm beginning to code in xCode 5 and I'm doing a really simple app. I just began and, when I try to test my game with iOS Simulator, the main page opens, but when I click on the button to launch the game, I'm redirected to xCode and this appears:

#import "AppDelegate.h"

    #import "AppDelegate.h"

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

and just next to it, this is written:

Thread 1 : Signal SIGABRT

I searched on internet and I just can't seem to find an answer.

Could someone help me please???
