should help you out I have an array of AnyObjects of NSDates and I am trying to convert to weekdays like (Mon, Tue, Wed..) , The xAxisDates array contains NSDate objects, therefore

code :

let date = formatter.dateFromString(i as String)

for i in xAxisDates {
    println(weekDayFormatter.stringFromDate(i as NSDate))
}

for i in xAxisDates {
    if let date = i as? NSDate {
        println(weekDayFormatter.stringFromDate(date))
    }
}

like below fixes the issue A date format string of @"MMMM" means that the string you're trying to parse is the full name of a month ("January", "October", etc).
You want something more like:

code :

yyyy-MM-dd HH:mm:ss

Using NSDateFormatter dateFromString

I hope this helps . This answer describes all the format specifiers in detail. hh stands for "hour (1-12, zero padded)" - so you can't write 15h here. If you wish to use a 24-hour time format, use HH instead.

code :

[dateFormat setDateFormat:@"EE, dd MMM yyyy HH:mm:ss ZZ"];

I wish this helpful for you
If you're working with fixed-format dates, you should first set the locale of the date formatter to something appropriate for your fixed format. In most cases the best locale to choose is en_US_POSIX, a locale that's specifically designed to yield US English results regardless of both user and system preferences. en_US_POSIX is also invariant in time (if the US, at some point in the future, changes the way it formats dates, en_US will change to reflect the new behavior, but en_US_POSIX will not), and between platforms (en_US_POSIX works the same on iPhone OS as it does on OS X, and as it does on other platforms).

code :

// String to Date
NSString *birthday = @"Jun 29, 2013, 8:45 AM";

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"MMM dd, yyyy, HH:mm a"];
dateFormatter.timeZone = [NSTimeZone timeZoneForSecondsFromGMT:0];
// Setting the locale to POSIX ensures that
// the user's locale won't be used
dateFormatter.locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"];
NSDate *birthdayDate = [dateFormatter dateFromString:birthday];

NSLog(@"birthdayDate:%@", birthdayDate);

// Date to String
[dateFormatter setLocale:[NSLocale currentLocale]];
dateFormatter.timeZone = [NSTimeZone systemTimeZone];
NSString *originalBirthday = [dateFormatter stringFromDate:birthdayDate];

NSLog(@"originalBirthday=%@",originalBirthday);
