NSDataDetection for Dates in Images with different Formats dependent of Locale?

I would like to convert a Date on an image to a Date type in Swift to store that data. I thought that I could use NSDataDetector for doing this, because I don't know the exact format which will occur on the image.
I had for example this Date: 01.08.2022 with the format: dd.mm.yyyy but if I use the NSDataDetector it was interpreted with the format mm.dd.yyyy
Is it possible to change that behavior so that the usual order of the numbers for the days and months for the region is used for interpretation?
Thanks for an answer

Issue with date format in input control

I have a report that takes date range as input control. But when I enter the date in the input control, its format changes automatically and error message is displayed (screenshot attached).
What's going wrong here?
Its because of the date format you have given in the iReport which is mm/dd/yyyy and default date format of JasperReport server is yyyy-MM-dd.
You can change the date format of JasperReport server which is controlled by the Locale and therefore the locale bundles.
To change the date format edit jasperserver_config.properties which is under
\jasperreports-server-cp-5.5.0\apache-tomcat\webapps\jasperserver\WEB-INF\bundles
These are the date formats in jasperserver_config.properties file:-
date.format=dd-MM-yyyy
datetime.format=yyyy-MM-dd HH:mm
calendar.date.format=%d-%m-%Y
calendar.datetime.format=%Y-%m-%d %H:%M

Is there a name for the date format "YYYY-MM-DD HH:MM:SS"?

For talking over the phone or to my co-workers, is there a short-hand name for this date format already established?
Names of other standard date formats would also be useful.
That is the ISO standard date and time.
ISO 8601

how to change the date format in the objective-c

after selecting the date from the date picker, i am getting the date in the format in view like yy/mm/dd .
i want to the date format in my view like mm/dd/yy.
how can i do this.
You can use the following snippet to convert the date to the format you desire. Note that month use uppercase 'MM' in the format:
[dateFormatter setDateFormat:#"MM/dd/yy"];
dateString = [dateFormatter stringFromDate:theDate];
For a full list of the formats available, have a look at the Unicode Standard. With a few minor exceptions, these formats are all supported on the iPhone.

How to change format of date/time?

I have this date and time format:
2010-05-19 07:53:30
and would like to change it to:
Wednesday # 7:53PM 5/19/2010
I'm doing this, which gets the current format:
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = #"yyyy-MM-dd HH:mm:ss";
but when I change the format, I end up with a null. For example:
formatter.dateFormat = #"hh:mm tt MM-dd-yyyy";
date = [formatter stringFromDate:formattedDate];
date will be null. I want to put the end result into an NSString. It would be nice if time and date could come out as separate properties so I can arrange them however I like. Any ideas on how I can change the formatting?
I think your formatting string is the problem. You should only use the characters you find in the table in UTS#35 Date Format Patterns. I tried your code and while the time hh:mm displays correctly, formatting stops at tt - not in the table!
If you really want characters in the format string that are not in the table you can escape them, like hh 'o''clock' a, zzzz - produces format like "12 o'clock PM, Pacific Daylight Time".

You have things backwards. If this is a date/time to be displayed to the user, you need to present it how the user wants it, not how you want it. For instance, most people outside the USA will be confused by MM-dd-yyyy particularly if the day is less than 13. Consider using -setDateStyle: and -setTimeStyle:. That way, the display string will come out as the user expects.
