If the drop-down has default value as empty/blank, unable to select any value from the picker wheel

Platform - iOS

OS - iOS 8

The drop-down I am working on by default has no value. I tried to click on the drop down and then do send_keys…does not work…but it works when the drop-down has a value(not empty).

How do you handle this?

Thanks in advance!

Found a solution…do a swipe, drop-down now has a value and then do send_keys.

picker_wheel = self.driver.find_element_by_class_name(“class name”)
