main.m

#import \<UIKit/UIKit.h\>

int main(int argc, char\* argv[])  
{  
@autoreleasepool {  
int retVal = UIApplicationMain(argc, argv, nil, @“AppDelegate”);  
return retVal;  
}  
}

Good morning, excuse me, I’m trying my application in the IOS simulator and I get that error? Does anyone know what that code is for? I would appreciate it, thank you
