Empty birthday field in creating new contact IOS

[wfrsnk]

In IOS 12.4 if i want to add a new contact, the contact form behaves strangely: birthday field is empty, but i set it in sending object like "birthday: { day: '12', month: '07' }"; if i tap to empty field, the application freezes until reboot it; if i ignore empty field and save contact, it saves and in phone contacts this one has correct birthday date.

In IOS 15.4 it works correct.

we aren't trying to support older versions of operating systems.

In my solution, versions IOS older, then 13.0 needs "year" key for correctly display at form and fix it. But this key breaks a form in versions after 13.0
