Answer 1

In Swift 5 and Xcode 10.2

In iOS 9.0 CNContactViewController navigation bar working properly, but not higher versions.

DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + Double(Int64(0.1 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC), execute: {

   //Set status bar background colour
   let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
   statusBar?.backgroundColor = UIColor.red
   //Set navigation bar subView background colour
       for view in controller.navigationController?.navigationBar.subviews ?? [] {
          view.tintColor = UIColor.white
          view.backgroundColor = UIColor.red
       }
})

navigationController?.pushViewController(controller, animated: true)

Here i fixed status bar background colour and navigation bar background colour. If you don't want status bar colour comment it.

The complete code is

func addPhoneNumber(phNo:String) {
    if #available(iOS 9.0, *) {
        let store = CNContactStore()
        let contact = CNMutableContact()
        let homePhone = CNLabeledValue(label: CNLabelHome, value: CNPhoneNumber(stringValue : phNo))
        contact.phoneNumbers = [homePhone]
        let controller = CNContactViewController(forUnknownContact : contact)
        controller.contactStore = store
        controller.delegate = self

        DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + Double(Int64(0.1 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC), execute: {

            //Set status bar background colour
            let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView
            statusBar?.backgroundColor = UIColor.red
            //Set navigation bar subView background colour
            for view in controller.navigationController?.navigationBar.subviews ?? [] {
                view.tintColor = UIColor.white
                view.backgroundColor = UIColor.red
            }
        })

        navigationController?.pushViewController(controller, animated: true)
    }
}
