Catch this on 12.0.1 (12A7300). Trying to understand what the reasons.... Find the solution - check all files in Assets, find the corrupted one and removed it from Assets. All work fine now.

In my application user may choose different color schemes. But if user choose color theme with dark background - he can't read black characters. Also if all texts in my application has red color I am need to repaint UIDatePicker texts in the same red color... So it is strange to me that we can't improve design of standard element...
