Hi,

In my project I noticed that date-picker component keeps crashing on a specific dates.
Sending this error message:
"Invalid calculation: number of calculated days is not dividable by the number of days in a week.'"

Initially I thought it's something with my project and so on. But after that I had created a new project without any lines of code.

Steps to reproduce the error:

Create new Xcode project
Open Main.storyboard
Drag datepicker from the "+"
Run project
tap over the datepicker and scroll to 1996

Note: This happens only if the date picker is with preferred style: compact and/or inline (default options).

I looked at video and did the test with the same DatePicker configuration.

No crash.

I tested with 12Pro simulator. No crash.

Could you post the complete crash log, it is not possible to read on the video.

I am also using 12.4 (12D4e)
Tested on Catalina 10.15.7 (19H114)

What is your MacOS version ?

Maybe you have an Xcode installation issue ?

This was an issue with UIDatePicker and certain timezones that was addressed in iOS 14.5, which was released earlier this Spring.

For any kind of date picker issue, please also post the locale of your device, the calendar you are using and the time zone your device is set to.
