The way to reproduce the issue is as follows: My app doesn’t declare any permissions for accessing Contacts ( I didn’t set up the Privacy - Contacts Usage Description key in Info.plist ). It just uses CNContactPickerViewController to bring up the contact picker, lets the user select a contact, and grabs the result. After that, you’ll see the Private Access message appears, as shown in the image. It only shows up on iOS 18; it doesn't happen on earlier versions.
