Error IOS simulator

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

same here, after upgrade to ionic 3.9.2
