Current behavior

The CalendarDatePicker doesn't work in an iOS environment where more than one Preferred Language is set via the Settings App.

Expected behavior

CalendarDatePicker works regardless of the Preferred Languages set.

How to reproduce it (as minimally and precisely as possible)

Download this sample: CalendarDatePickerLanguageBug.zip

Go to your device Settings App > General > Language and regions and set the following:

  • Preferred languages: English, Italian

  • Region: United States

Deploy and run the sample on iOS

It crashes with the following error:
