Convert the 'futureDate' object to a string object named 'dateString'.

Here's my code that promoted me up until step 4/4 on the coding challenges.

NSTimeInterval secondsPerDay = 60 * 60 * 24; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; // Add your code below NSDate *today = [NSDate date]; NSTimeInterval secondsPerTenDays = 60 * 60 * 24 * 10; NSDate *futureDate = [[NSDate alloc] init]; futureDate = [NSDate dateWithTimeIntervalSinceNow:secondsPerTenDays]; [dateFormatter setDateFormat:@"mm/dd/yyyy"];

however, when i type my code for the question above,

NSString *dateString = [dateFormatter stringFromDate:futureDate];

it tells me that now my step three is wrong.
