ios – Displaying restricted contacts record in UIKit

I’ve an app that was written in UIKit. It is too giant, and it will be a lot too time consuming at this level to transform it to SwiftUI.

I need to incorporate the brand new restricted contacts into this app. The best way it is at the moment written every part works high-quality aside from exhibiting the restricted contacts within the contact picker.

I’ve downloaded and gone although the Apple tutorial app however I am having bother pondering it by into UIKit. After a few hours I made a decision I need assistance.

I perceive I want to tug the contact IDs of the contacts which might be within the restricted contacts record. Undecided how to try this or tips on how to get it to show within the picker. Any assist can be drastically appreciated.
