ios – UIPickerView present empty label swift

UIPickerView not working for IOS 15.5 my code was working IOS 7.0
Since i up to date to macOS Monterrey 12.5 and code 13 UIPickerView not working as anticipated anymore.
It was a easy UIPickerView for choosing a quantity.
No error or warning is acquired.
Solely present an empty grey label.

I would like so as to add one thing within the code ?
