Im getting the error : Bummer! Your date calculation seems incorrect. Are you using the product of 10 and 'secondsPerDay'?
but when i run the code below in my Xcode the code runs correctly and im getting 27-05-2014 (10 days from today).
NSTimeInterval secondsPerDay = 60 * 60 * 24 * 10; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; // Add your code below
NSDate *today = [[NSDate alloc]init];
NSDate *futureDate = [[NSDate alloc]init]; futureDate = [NSDate dateWithTimeIntervalSinceNow:secondsPerDay];
i don't know what the problem is.

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
// Add your code below
NSDate *today = [[NSDate alloc]init];
NSDate *futureDate = [[NSDate alloc]init];
futureDate = [NSDate dateWithTimeIntervalSinceNow:secondsPerDay * 10]; // <--- add * 10 after seconds var.
See short comments, hope this helps.

Courses Plus Student 10,224 PointsTry this:
NSTimeInterval secondsPerDay = 60 * 60 * 24;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
// Add your code below
NSDate *today = [NSDate date];
NSDate *futureDate = [NSDate dateWithTimeInterval:secondsPerDay * 10 sinceDate:today];
First time I use the backtick and to find it on French canadian keyboard, just mess
