Why top Navigation Bar disappear when do some action on the view using Swift?

Question

I have ViewController which has one button to navigate to CNContactViewController every thing works good I can go back and press the button again and so on .But my problem when I do one action on the CNContactViewController which is Share Contact the top navigation bar will disappear and for sure I'll stuck in this view .. this is the code:

    @IBAction func dothis(sender: AnyObject) {

    let contact = CNMutableContact()
    contact.givenName = "first Name"
    contact.familyName = "Last Name"
    contact.phoneNumbers = [CNLabeledValue(
        label:"Mobile",
        value:CNPhoneNumber(stringValue:"123456789")),
        CNLabeledValue(
            label:"Work Phone",
            value:CNPhoneNumber(stringValue:"1234"))]

    let workEmail = CNLabeledValue(label:"Work Email", value:"ex@whatever.com")
    contact.emailAddresses = [workEmail]

    let controller = CNContactViewController (forContact: contact)
    controller.contactStore = self.store
    controller.allowsEditing = false

    controller.displayedPropertyKeys =
        [CNContactPhoneNumbersKey,CNContactEmailAddressesKey, CNContactPostalAddressesKey]

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

}

Do I need to implement something more for share contact and other actions on the CNContactViewController ?

Notes:

1- All actions on contact card work good like Call or Send Message except Share Contact causing the problem.

2- When I compare the actions on my VC with the Contacts app I notice that the pop up options view of Share Contact comes over the navigation bar but in my app the options view come behind the navigation bar .

See Contacts app on the left and my app on the right :

My Project file : Here it's small project

are you hidden the navigation bar in anywhere in your CNContactViewController — Anbu.Karthik, Sep 07 '16 at 08:37
@Anbu.Karthik This is the only code I have , I made new project has one class which has this action to make sure the problem not in my old code — Zizoo, Sep 07 '16 at 08:39
Are you seeing any error messages in the console? Your IBAction, do you also have a segue to the `CNContactViewController` in the storyboard? — Fogmeister, Sep 07 '16 at 08:56
@Fogmeister No errors showing on console + no segue in the storyboard — Zizoo, Sep 07 '16 at 08:57
@fogmeister you can see the project in the question , only one VC and one class — Zizoo, Sep 07 '16 at 09:07
I download your demo, and test it with Xcode 8,iOS 10.The navigation bar will reappear when you click cancel button. Maybe you should try it. — wj2061, Sep 11 '16 at 11:06

This is a bug according to this https://stackoverflow.com/a/33762209/3378099

Here is a non-elegant solution:

Create an new class extending UINavigationController
Assign it to your NavigationController in Storyboard
Override function func setNavigationBarHidden(hidden: Bool, animated: Bool)

I did update Xcode to version 8.0 with Swift 3 and the problem solved without changing the code.
