I am trying to implement CNContactViewDelegate to be able to show detail of the CNContact. And apparently, I am the first one to implement it with SwiftUI and getting problems. Anyway, I can see the detail of CNContact with using UIViewControllerRepresentable but I have an issue with the NavigationBar, which there is gap between the Contact's image and StatusBar -because of the NavigationBar and NavigationLink I think- and this gap is not there in the native Contacts app and apparently in this link that implemented the framework in UIKit. 
Here is the code;
struct ContactsListView: View {
    @ObservedObject var contactsModel: ContactsViewModel
    var body: some View {
        NavigationView{
            List {
                //After some ForEach's and Section's
                //This view is working. 
                NavigationLink(destination: ContactDetailView(contact: self.$contactsModel.contacts[sectionIdx].contacts[contactIdx])) {
                    Text(self.contactsModel.contacts[sectionIdx].contacts[contactIdx].givenName)
                }
            }
            .navigationBarTitle("Contacts")
        }
    }
}
struct ContactView: UIViewControllerRepresentable {
    @Binding var contact: CNContact
    func makeCoordinator() -> ContactView.Coordinator {
        Coordinator(self)
    }
    func makeUIViewController(context: UIViewControllerRepresentableContext<ContactView>) -> CNContactViewController {
        let controller = CNContactViewController(for: contact)
        self.navigationBarHidden(true)
        return controller
    }
    func updateUIViewController(_ uiViewController: CNContactViewController, context: UIViewControllerRepresentableContext<ContactView>) {
        print(context)
    }
    class Coordinator: NSObject, CNContactViewControllerDelegate {
        var parent: ContactView
        init(_ contactDetail: ContactView) {
            self.parent = contactDetail
            self.parent.navigationBarHidden(true)
        }
    }
}
In the ContactView, both of those self.navigationBarHidden(true)'s are not working. As an example of the problem here is the native app's screenshot;
And here is the result of my code;


 
                        
As the question is got an upvote I thought I can share my half way solution. This solves the gap however during the transition to detail there is a glitch of navigation bar with background color. After the transition it is becoming clear.
