If you want to output a date in a predictable format, you should use a date
formatter. When I ran a sample app under the simulator for tvOS 13 in Xcode 11
beta 5, I got these results for the specified locales:
2019-08-20 19:51:05.637667-0700 TestDateDescription[32894:2579867] ar_AE: The
date is now 2019-08-21 02:51:05 +
2019-08-20 19:51:42.350744-0700 TestDateDescription[32899:2580909] fr_FR: The
date is now 2019-08-21 02:51:42 +
2019-08-20 19:52:13.121429-0700 TestDateDescription[32905:2581496] en_US: The
date is now 2019-08-21 02:52:13 +
This was the line of Swift I used:
NSLog("%@: The date is now %@", Locale.current.identifier, NSDate())
For a predictable format in logs, I’d suggest using NSISO8601DateFormatter.
