UISearchBar's set_cancelButtonText: ivar is prohibited

uisearchbar ios 13
uisearchbar background color
uisearchbar is active
uisearchbar vs uisearchcontroller
uisearchbar programmatically swift 4
uisearchbar scope bar
uisearchbar search icon position swift
uisearchbar cancel button

Previously in iOS 12 the same code was allowed, but now when i try to run the same code on iOS 13 it crashes giving me the same error:

Terminating app due to uncaught exception 'NSGenericException', reason: 'Access to UISearchBar's set_cancelButtonText: ivar is prohibited. This is an application bug'

Which is related to this line of code:

searchController.searchBar.setValue("Cancel".localized, forKey:"_cancelButtonText")

Now i know the access of setValue is now prohibited but how is it possible to overcome this crash and change the title of cancel button, since there is no property included in the searchbar.
