I'm seeing these crashes also, but only for Beirut (!). You can recreate by setting the device's time zone to Beirut, while leaving the current Region to United States (or any region other than Lebanon).
Force current Region to Lebanon in Edit Scheme - Options - App Region and it doesn't crash. But setting the picker's locale to en_LB (Lebanon) doesn't help.
There must be something specific about the mismatch of time zone and region for Lebanon but I haven't found it. A (poor) workaround might be to identify the mismatch and switch the picker.preferredDatePickerStyle to .wheel in that case only.
