NSDateFormatter dateFromString returns nil in iOS 13 issue

Question

NSDateFormatter dateFromString returned a NSDate object before iOS v13 update. But in iOS v13 and v13.1 it returns nil NSDate object. How to resolve this issue?

changing Date & Time from "Settings -> General - > Date & Time" then Unticking 24-Hour Time resolves this error.

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];

NSDate *date = [formatter dateFromString:@"2019-10-02 09:10:15"];

Expected a not nil *date

iOS v12 and older versions didn't have this issue, setting Locale was not mandatory to get the date formatted.

If unticking 24 hour fixes the error, replace your hour unit with `hh` — Desdenova, Oct 02 '19 at 11:31
@Desdenova using "hh" shows wrong time in output for afternoon times(ex: 2019-10-01 14:36:56) — Kasun Rangana M W, Oct 02 '19 at 11:45
add a locale to your Date Formatter like `[formatter setLocale:[NSLocale localeWithLocaleIdentifier:[NSLocale currentLocale].localeIdentifier]];` — Hyder, Oct 02 '19 at 11:55
@Paulw11 it works fine when the time format is not set to "24-Hour Time" in "Settings" — Kasun Rangana M W, Oct 02 '19 at 11:59
No, it works for me regardless of the time setting on the device. — Paulw11, Oct 02 '19 at 12:00
@hyd00 setting a Locale your way solves the issue. I found another way too -> [formatter setLocale:[NSLocale localeWithLocaleIdentifier:@"en_US_POSIX"]] — Kasun Rangana M W, Oct 02 '19 at 12:08

I found a way to resolve this issue.

[formatter setLocale:[NSLocale localeWithLocaleIdentifier:@"en_US_POSIX"]];

@hyd00 setting a Locale your way also solves this issue. Thanks a lot.

[formatter setLocale:[NSLocale localeWithLocaleIdentifier:[NSLocale currentLocale].localeIdentifier]];
