NSDateFormatter- dateFromString returning nil when set AM/PM

Question

I have the following string 2016-10-26T16:01:18.361Z and works with the folowing code:

formater = [[NSDateFormatter alloc] init];
[formater setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"];
[formater setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];

But using the same string and the same formater is returning nil when system clock settings is changed to AM/PM

What format should I use?

Unrelated but do NOT quote the `Z` in your format string. It should be `@"yyyy-MM-dd'T'HH:mm:ss.SSSZ"`. — rmaddy, Nov 29 '16 at 16:28
That's why I said my comment wasn't related to your immediate issue. That will be solved by setting the formatter's locale to `en_US_POSIX`. — rmaddy, Nov 29 '16 at 16:33

That code works just fine for me on the simulator when it's set to AM/PM mode. — Duncan C, Nov 29 '16 at 16:57

As @rmaddy said this code works fine.

formater = [[NSDateFormatter alloc] init];
[formater setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSSZ"];
[formater setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
[formater setLocale:[NSLocale localeWithLocaleIdentifier:@"en_US_POSIX"]];
